Added LoRa SPI1 pins to variants, uncommented GPIO36+ in pins.cpp

This was necessary for the radioLib examples of peer-to-peer (transmit/receive) to work with the expLoRaBLE.

Library found here: https://github.com/jgromes/RadioLib

In addition to enabling SPI, it also needed D40 available to fix a DIO1pin/timeout/IRQ related issue.
