Level fix and beep, RSSI avg fix (#2027)

* fix average value being overflow'd
* fix audio and mod changes, preps for beep mode
* fixed beep_freq range, added a stop and set a variable sooner
* added support for audio beep messages
* better scaler for beep
* added bip squelch and saving of bip squelch and audio mode
* saving modulation, fixing audio
* added save and restore of bandwidth
* simpler ctcss clean on change mode
