RadioHead library out of date #13
Description
We're currently using radiohead 1.61 modified by Paul Stoffregen https://github.com/PaulStoffregen/RadioHead
This was done to test the code on a board where the LoRa chip is connected to SPI1 but is not needed anymore
We should use the latest version https://www.airspayce.com/mikem/arduino/RadioHead/
The update might break some things, .lastRssi() in particular
