M5 LoraE220 support (maybe other LoRa device?)

[igorolhovskiy]

Is your feature request related to a problem? Please describe.

I'd like to have LoRa stress and scan tool. Idea is to receive messages over LoRa (store-?), scan through channels for info (if any), send individual messages (chat?) and have a stress tool (spam) to test external gateway throughput.
Describe the solution you'd like

Additional LoRa app in Bruce firmware.
Additional context

Willing to sponsor this development due to lack of C programming skills (and time).
