Add Auto Focus

[jerryneedell]

I've been working on adding Auto focus support and have it working OK in the jerryn_af branch on my fork
https://github.com/jerryneedell/Adafruit_CircuitPython_OV5640/tree/jerryn_af

I need to add a file to the repository that is used for initializing the auto focus
ov5640_autofocus.bin
ov5640_autofocus.bin.license

but pre-commit fails in the "reuse" check when these files are added to my branch.

these same files are used in the pycamera library

where it is set up as a package.

Do I need to set this up as a package as well for it to pass?
I suppose that will make it cleaner to install.

Ah -- I fixed the issue with the license.
Still not sure how best to organize this. Would it be better as a "package" so the ov5640_autofocus.bin file is more easily included?

Ya, I guess that the bundling code expects source files to be in the package folder. I'm not exactly sure how CPython normally does this.

standard python can use importlib.resources.files() but porting this to CircuitPython would be a lot of work, compared to the simple string manipulation method of finding a filename next to a .py file in a package.
