Change `furi_hal_subghz_is_frequency_valid` and `furi_hal_subghz_set_frequency_and_path`
Reminder, the unofficially supported freq are 281-361 MHz, 378-481 MHz, and 749-962 MHz
281000000 - 361000000<br>
378000000 - 481000000<br>
749000000 - 962000000
```

Don't forget to add your new freq to the [user settings](https://github.com/UberGuidoZ/Flipper/tree/main/Sub-GHz/Settings) file.
