Have mpy-cross Available For Download

[sommersoft]

We should have compiled versions of mpy-cross available to download.

If I understand correctly, previous availability was done manually by adding it to a release's assets. Since they aren't built dynamically, I would guess that they could live here in assets/.

This would be very helpful for our projects that use non-express boards

GitHub Actions can run jobs in Linux, Windows, or MacOS. It says ARM too, so maybe we could build an RPi version (?).

mpy-cross binaries, built for every merged PR and release, are now in https://adafruit-circuit-python.s3.amazonaws.com/index.html?prefix=bin/mpy-cross/

[dhalbert]

I'm thinking that links to the mpy-cross downloads should be on circuitpython.org somewhere, though, maybe on the libraries page??

Yes it should be on circuitpython.org or better referenced or this kind of thing take place: https://www.recantha.co.uk/blog/?p=20904
