5a3153c8b9 Find line segments more stable
Switched the find line segments algorithm to something more stable using
the standard LSD algorithm that's used by OpenCV.

7dff089e6f Removed QRCodes from the OpenMV Cam M4.
They don't really work that well on it anyway due to having to use a low
res. This makes room for more basic CV features on the M4 which it can
run.

5f4e690fa1 Add find circles.
Now you can find circles with your OpenMV Cam! The alrogithm can eek out
about 7 FPS on a 160x120 image which is quite impressive given how
computationally expensive circle finding is...

cd4ad0dff3 Add linear regression
For easy line following mainly. In non-robust mode the line is computed
using least squares. In robust mode the line is computed using the
Theil-Sen median of slopes method. We do not use the Siegel Median of
Medians operation because it costs more CPU time... but, more
importantly there's no way to improve the centroid estimate so even if
the slope is more robust the line will be drawn in the wrong place.

dc6ab59cfd Add Image Writer/Reader
These two new classes allow you to record image data for later viewing
at the same speed the image data was recorded. Unlike GIF/MJPEG the
image data is stored on the file system completely uncompressed in
native frame buffer format making super fast reading and writing
possible. Recording VGA Grayscale at ~13 FPS is possible along with
playing it back. (That's about 30 Mb/s folks).

...

The motivation for writing these scripts is so that you can record video
of something like a line following track, take that video home, and work
on computer vision algorithms for that data.

These classes should make it a lot easier to use the camera at home now.

31b7b5bf3e Improved find_lines
Frame rate now can hit 30 FPS when JPEG compression is off. Merging of

71e795812f April Tag Release Fixes
Everything works. Running out of memory is fixed and the rotation value
is valid now. For 320x240 operation on the STM32H7 we're going to need
on the order of 1 MB in the entire frame buffer. The code is designed to
handle us getting this amount of memory without any new changes for
320x240 support.

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.

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.
