* Added support for the LR1121 radio

Added support for the LR1121 radio, tested as functional with an E80-900M2213S from CDEbyte.

* Swap PNG for PDF

* remove PNG

* put TCXO voltage to 1.8, as in example file

It worked at 1.6v, but ¯\_(ツ)_/¯

* Hopefully this will appease Trunk

* Update rf switch pins and Schematic
