radio chip selection

Radio chip driver is not included, allowing choice of radio device.
If you're using SX1272 or SX1276, then import sx127x driver into your program.
if you're using SX1261 or SX1262, then import sx126x driver into your program.
if you're using SX1280, then import sx1280 driver into your program.
if you're using LR1110, then import LR1110 driver into your program.
If you're using NAmote72 or Murata discovery, then you must import only sx127x driver.
If you're using Type1SJ select target DISCO_L072CZ_LRWAN1 and import sx126x driver into your program.
