Should we add fix for SF=6?

[jerryneedell]

There is a PR in Adadruit_CircuitPython_RFM that fixes a known issue with Spreading Factor = 6

adafruit/Adafruit_CircuitPython_RFM#10

Should this also be implemented here?
It will increase the size of the library and further impact the smaller M0 build (feather M0 rfm9x)?

Users who need SF=6 can use the Adafruit_CircuitPython_RFM library but that will not run on the small M0 boards.

SF=6 is not supported by the RadioHead Arduino library so without it, the adafruit_rfm9x library is still "compatible" with Radiohead ;-)

I don't know how much it will increase the library - likely a few 10s of bytes.

How you would like to proceed?

Let's not fix it now due to code size increase and it not being needed for RadioHead compatibility. Instead, let's leave this issue open in case anyone comes along needing this. Once they do, we can decide if and how to fix it. Thanks!
