Get firmware image to a release state

[samaclea]

• [x] Get test python script written
• [x] Get a way to get test script on initial firmware write
  • It looks like we could create some of our own code they way they set the initial code.py here: https://github.com/adafruit/circuitpython/blob/5f762811a67ba283ef76de6b01b838f6ab4192d2/supervisor/shared/filesystem.c#L157
• [x] Implement OTA Updater changes listed in #2
  • Get with @pmcknig1 to talk about hosting code on our server instead of github

Updater code works well when pulling from Github, and shouldn't be too hard to refactor to pull from a server we control if we need to.

As for getting our code on the badge with the initial firmware install so far we need 7 files:

• boot.py
  • Allows updater to run
• secrets.py
• code.py
  • Code for the factory to test the functioning of the badge
• lib/updater.py
  • Updater code
• lib/adafruit_st7735r.mpy
  • Display driver
• lib/pdepd.py
  • EPD driver
• lib/flavortext.py
  • Output funny quotes :)

Test script lives in src/test_badge.py for now, but I will probably move it to tools later because I don't think we need to ship it with final badge code.

Script tests:

• Neopixels
• Buttons (1-4)
• LCD Screen
• Epaper Display

Script doesn't test:

• UART (though this will be used to flash the ESP32)
• STEMMA connector
• Boot/RESET buttons

Swapped to firmware version 8.2.10 while debugging firmware, not sure if it had any affect but it's probably good form to use the stable branch and not beta.

I am now able to get files included on initial firmware write, I do this by modifying circuitpython/supervisor/shared/filesystem.c with the byte contents of files in firmware/init_files/. Doing this manually is laborious and annoying so I created the tools/py2fs.py script to do this for you. Instructions are here.

Ooops still need to get info from @pmcknig1 on badge network stuff.

Firmware hex was delivered successfully to the fab.
