Add T-Beam BPF - 144-148 Mhz LoRa @ ~37 dBm (5 Watts) (#10558)

Browse Source 
* Add T-Beam BPF (144-148 Mhz LoRa)

* minor correction to fix compiler warnings

* Add T-Beam BPF (144-148 Mhz LoRa)

* minor correction to fix compiler warnings

* Add ITU regions for this device and make GPS work.

* Switch pin after defining it as output

* Lora CS is indeed 1, SD Card CS is 10

* Include the back option.

* Fix compilation with pioarduino (USB_MODE)

* Default ham to narrow_fast

* Default PROFILE_HAM to slot 17

This is an appropriate default in the USA but not the EU.

The slot override really should follow the region itself, not the regionprofile.

* Fix for ITU 2/3 split

* Add ITU region options to MenuAction enum

* Add HAS_HAM_2M definition to variant headers for 2M support

* Re-add PROFILE_HAM regionprofile

Accidentally removed in last merge

* Trunk fmt

* Initial default slots

* Switch to TinyFast

Still need to flesh out the default channels

* Adjust slotOverrides for TinyFast

* RadioLib doesn't accept 15.625 kHz

Use 15.6 instead

* Set RF95 pins for T-Beam Supreme

May cause regressions!!

* Remove other-variant changes (BPF-only)

These have been moved to other PRs

* Remove mismatch guarding (we need a more comprehensive approach)

* Add comment back

* Add template for PA curve

* This is a 5-6W radio!! Add TX_GAIN_LORA

* Trunk fmt because NomDeTom hates emdashes
