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.

80cb701d3b Add missing cam functionality
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
do for now.

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.

367e5fdd3d Improved JPEG capabilities.
* Added the ability to control the quality on JPEG functions... However,
due to our JPEG implementation this doesn't seem to help. 90% JPEG
quality images and regular images should be about equal. But, you can
see heavy degredation with 90% still. E.g. text is unreabable. Not
exactly sure why this is happening but it can be fixed later.

* Changed the compress() function to compressed(). Also, it now
compresses using FB_Alloc to prevent realloc issues when compressing.

* Added new compress() function. This function compresses an image in
place and if that image is the frame bufffer then it will update the
frame buffer bpp value to reflect the image was compressed. Users can use
this function to basically finalize the frame buffer and then pass the FB
to functions that need to send image bytes. The benefit of using this
function is that it should allow higher quality JPEGs and let everything
run at a faster speed while connected to the IDE.

I made this function to speed up WiFi. However, I encountered a bug with
the winc.send() method. It appears to zero the bytes it sends. I didn't
debug further except to verify that the image data became zero after
calling send.

2fa8227c7b Add AWB/HMirror/VFlip
Added setters for these camera settings. AWB is necessary for color
tracking to work correctly. AGC still runs, which causes lighting
shifts. It may need to be disabled too. Not sure... if I want to do that
or not however, because without it lightning won't get normalized to
remain at a certain level. So, turning AGC off may cause issues in other
ways.

a4ea3e0e20 Add filter functions
* Filter functions bypass the default line processing in sensor.c, and pre-process lines.
* Processing is done on the fly, i.e. filters are called from after each line is received.

ed69e4b15a Transfer raw frames line by line.
* Add HAL_DCMI_Start_DMA_MB to allow line by line transfers for
  raw frames using DMA double buffering feature.
* This means bigger grayscale resolution that would not otherwise
  fit into RAM.
* YUV to Grayscale conversion on the fly (as the frame being read).
* It's possible to perform differencing (and maybe JPEG) on the fly.
* Additionally, FPS for grayscale should be exactly like RGB
  (since there's no additional step after capturing the frame)
