Added SAMD21 ProRF 1W

However, I didn't do anything to the .json stuff... may still need to do that. But at least a working board definition is in there.

Includes definitions for:
E19_SPI (the hardware SPI port connected to radio module)
E19_RESET, E19_CS, E19_TXEN, E19_RXEN, E19_DIO0, E19_DIO1, E19_DIO0, E19_INT (pin numbers connected to the hardware)

FLASH_SPI, FLASH_CS
