RFM9x -- freeze library into build

[jerryneedell]

This freezes adafruit_bus_device and adafruit_rfm9x into the build for the feather_m0_rfm9x.
I had to take out several modules.
At this point, pulseio is removed. It may be possible to put it back once #3236 and #3237 are implemented. Right now some of the larger translations will not build with it and it does not work on the SAMD21 anyway. We can revisit this.
The main downside to removing it is we cannot support the DHT sensors.

I waned to get this out so it can be reviewed and be available for anyone to test.

adds Adafruit_CircuitPython_RFM9x to the frozen folder

[brentru]

@jerryneedell I'll be testing this today, added to TODOs

[brentru]

@jerryneedell Was too optimistic, will get to this tomorrow

[brentru]

@jerryneedell Ok, I checked out the branch and built the uf2. Had to delete default images folder to fit the simpletest code.py for the RFM9x.

Importing adafruit_rfm9x at the REPL throws the following ImportError

Adafruit CircuitPython 6.0.0-alpha.2-295-g5cf41c0d1 on 2020-08-17; Adafruit Feather M0 RFM9x with samd21g18

Not sure I understand where the “images” folder came from.
I'm confused. So you can't find the library after you built it?
Are you sure you built it from the PR?

You have a different commit than I do -- see comment below.

@brentru just tested #3237 on an rfm9x build with pulseio enabled and it can now support the DHT sensors.
perhaps we should hold off on this until #3237 is merged and I can see if I can fit pulseio back into the build.

[brentru]

Works! Thanks for making room

[brentru]

perhaps we should hold off on this until #32327 is merged and I can see if I can fit pulseio back into the build.

@jerryneedell I don't see any learn guides/projects which utilize the DHT+LoRa RFM9x (aside from TTN ones, and those should be run on the SAMD51). Are you OK with merging this as-is, and we can create another PR to fit pulseio after?

Yes -- absolutely -- go ahead -- pulseio may not fit anyway
merging it now would be my preference.
