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

* 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 Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> * 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 --------- Co-authored-by: Thomas Göttgens <tgoettgens@gmail.com> Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>
