Adding additional frequencies (TX/RX)

Official firmware now uses a different method for region locks. Per Aleksandr Kutuzov (skotopes):

Mobile app uses Phone/SIM region with fallback to GeoIP.
Desktop uses GeoIP and fallback to System.

This data is stored in the .region_data (hidden) file within internal storage and is set when connected to Desktop/Mobile per above.
If you're having issues with regional retrictions that do not match your region, you can use the region_data_null file here.
Simply download and rename it to .region_data then replace the one currently in your internal storage.

NOTE: This will be overwritten each time you sync to the mobile app or qFlipper! Use strictly for testing/verification purposes.

Note: You must be on the latest release!

Some changes I made to the available frequency settings (including unlocking them all). The file is found here:

Officially supported frequencies: 300-348 MHz, 387-464 MHz, and 779-928 MHz (from CC1101 chip docs)
Unofficially supported frequencies: 281-361 MHz, 378-481 MHz, and 749-962 MHz (from YARD Stick One CC1111 docs)

Official & Unleashed currently do not allow anything outside of the officially supported CC1101 specs.
RogueMaster allows unofficially supported frequencies with the extend_range file.

NOTE: Going outside the supported frequencies may DAMAGE YOUR FLIPPER AMP.
Please understand what you're doing if trying to break out of official frequencies.

You'll need to edit some code and recompile if you want to break outside of the officially supported frequencies. Proceed with caution.

CAUTION within 402-408 range!
Medical devices can operate here.

This range is purposefully not included in my file above.
