b230de3b42 Add binary format to sensor.
* This format is for use in the Image Lib module since sensor is where
we put the image types.

Will work on the lepton and global shutter drivers next.

Now you can rotate and image by 0, 90, 180, 270 degrees along with
vertical flip and horizontal mirror. This method works in place or out
of place.

aa7386ac5f Add cartoon filtering
It's not as good as mean shift filtering but can approximate it if you
heavily control the image image lighting conditions. That said, it's a
lot faster and less memory than mean shift filtering.

09c9d97a70 Add bilateral filtering support
Runs faster than median filtering with a large kernel size. That said,
if sigma is set to low for the particular scene you can get corrupted
pixels if there's too much change in a particular kernel area. Tried a
few things to filter this out but was not successful. Not sure how to
fix... but, turning the sigma up hides the issue. It has something to do
with zeros in the luts used to speed the algorithm up causing
instability.

d7159fba3e Upate filtering operations
Binary images are now handled. Cleaned up and optimized code. Some speed
gains after shifting to multiplies and not using int8_t.

Added a sharp and unsharp mask feature. Fixed up guassian. Added a
laplacian operation for edge detection.

Heavily upgraded the drawing features onboard the OpenMV Cam. We now

parameters you need. Finally! You can make big text fonts.

* Added shape fills
* Added text scaling
* Added draw arrow.

e0e112468e Argument Parsing Done Correctly
All of our argument parsing code has now been updated to handle
positional as well as keyword arguments in our python libraries.

Basically, python allows you to pass some number of positional arguments
to functions/methods followed by keyword arguments (you cannot have more
positional arguments after keyword arguments). Previously, our code
would only look for keyword arguments. Now, it works better and will
grab as many positional arguments as it can followed by processing
keyword arguments. Note: If the case of a positional argument value for
a parameter being passed followed by a keyword for that same parameter
the keyword value is taken (since it comes aftward).

Because arguments were passed in keyword form before this update has no
affect on current code. However, moving forward, argument positions are
now locked and cannot be moved around.

397abe4746 Cleanup Math Operations
Add binary image support to the math operations and updated them to
support masks. Replace now also support mirroring operations. Finally,
adding missing basic math ops like add/sub/mul/div. The operations are
designed to work as image blending operations so they take care of
scaling their output accordingly.

fb3d0776f0 Overhaul Binary Functions
Binary() can noew zero things so you can remove bright lights. All the
line ops (and/or/xor/etc) accept masks. Erode and dilate now accept
masks. And finally, you can now pass arguments versus keywords for folks
who don't read the documentation. Also, the binary image type is now
supported for these methods.

I'm putting in all this work because I saw the need for it when I was
doing shadow removal.

Note: Some effort needs to be put into optimizing the py_image.c code
soon. This is on the todo list before the next release.

(along with an invert arg) to control what gets put into the histogram.
