RadioLib SX126x Spectrum Scan
This code perform a spectrum power scan using SX126x.
The output is in the form of scan lines, each line has 33 power bins.
First power bin corresponds to -11 dBm, the second to -15 dBm and so on.
Higher number of samples in a bin corresponds to more power received
at that level.
