02af722fe8 Fixed fb_alloc() with mark for recently re-worked code.
I also tested the firmware for about an hour to make sure there was no
stack leak.

Note that I prefer for fb_free() to still be called versus
fb_free_till_mark() doing that for you in the code.

For functions without this fix they will just free the entire fb_alloc
stack when an exception happens. For functions with this fix they will
only free up to and including the mark. Since there are no places in the
firmware where you could start building a second fb_alloc stack when one
is already in place this point is moot currently. But, if we do
something like that in the future the problem will have already been
solved.

Any new code or re-worked code should use the mark function.

d6b49adefa Speed up lens_corr.
Speed up the algorithm by fixing the abs() issue. Do not use that
function in any of your code. It by itself cut the speed of the code
in half. I don't know what's in that function but I'm guessing it does
ABS of a float using ints or something.

I made the zoom parameter functional now too so you can use lens_corr to
zoom in on the image. Argument parsing is handled too. Finally, I
updated the only script where this is used.

Note that I'm able to get more than 10 FPS at 160x120 on the M4 and 15
FPS at 160x120 on the M7. Previous this was at about 5 FPS and 7.5 FPS
respectively.

0111084125 Updated stats code
We now have a method to get an the normalized histogram of an image
patch. The histogram is returned as an object with methods too. You can
then get the stats off of the histogram or just get the CDF of it. The
CDF is particularly useful for automatically chaning the the color
tracking bounds.

945a83c789 Add keypoints filtering function.
* This function filters keypoints far from the centroid, it's very useful for finding an accurate bounding box for an object.
  If a bounding box for the object is not needed, the centroid can be used instead since it's not affected too much by outliers.
* The filter finds the centroid of all the previously cross-matched keypoints then finds the mean, variance and standard deviation,
  it then filters keypoints with a distance higher than standard deviation from the centroid.

af15ec6eb3 New Blob Code
The new API is backwards compatible with the previous one except for
advanced features. The new blob code uses a flood fill algorithm that is
3x faster in filling out blobs that the previous code. On the M7 the
performance cap of 30 FPS is usually reached.

Additionally, blobs are objects with named attributes now so you don't
have to index access them anymore. However, index access is still
supported.

7af818c4d8 Finished up optical flow code.
* Added pooling functions to make getting small images easy. set_binning
works too... but, it zooms in way to much. pooling functions aout you to
shrink the image while not zooming in.

* To make the pooling functions easy to use I created a version that
pools the image out of place and one that pools the image in place. The
inplace pooling function can work on the frame buffer (see edits to
sensor.c)

* I added the code to do hann windowing to the FFT lib. However, I
commented it out after it improved performance by basically zero.
Specialized windowing stuff will only come in handy for folks trying to
tune their algorithm... not in general for everything.

* I added subpixel resolution for the phase correlation code. You can
now track the image movement really precisely. Additionally, I fixed up
the displacement outputs to give expected results. I also added a QoR
output for the displacement code so that you can know when the results
are bad.

* Finally, an example script has been added to show off the features.

15aed91efd Fixed FFT and Phase Correlation!
There were some mistakes, they are fixed now. FFT 1D and 2D work
flawlessly. No problems with that code anymore.

As for phase correlation I need to study how to interpret the output
better. The function generates noisy results once you move the image too
far and I'm not quite sure if I have the code right for detecting
positive and negative displacements.

45fdcc973e Add FFT Code and Phase Correlation Code
The heart of the 1D FFT works. I tested this on the PC. However, 2D FFTs
may have issues and the phase correlation algorithm does not generate
the expected results. That said, most of the work is done. Stuff just
needs to be deubgged.

The FFT lib is designed to handle up to 1024 point real FFTs and 512
complex FFTs. As for 2D FFTs, we can do up to 64x64 pixels. After which,
we don't have enough RAM to handle them because they use up about 128KB
each.

Things to do... the 2D FFT needs to be verified. So, we need to run an
image through it and then back again to verify that there are no
problems. Then we need to compare the 2D FFT output with another 2D FFT
algorithm on the PC...

Once the FFTs are known to be good we then need to make sure the phase
corelation algorithm outs the correct results. We need to test that with
multiple shifted images, etc.

Added the ability to turn AGC off. Kinda will need the ability to restore
AGC settings back to user specified ones in the future... but, this will

Added the ability to turn AEC off. Objectively this function probably
won't be used. But, in low light situations it can help.

Added get_fb() to allow you to get the last image snapshot returned.

There was some old exposure function in the code that was getting
optimized out. So, I deleted the used methods that didn't have any code
in them and commented out the only method that did.
