Looking glass beep

[gullradriel]

This add a squelch based beep option on Looking Glass:

• It can be enabled/disabled
• Squelch level before activating beep is adjustable
• Detection use the whole range
• In order to add the necessary volume field, I took out the (IMHO) not useful 'STEPS'

That 'map' function I added should be templated somewhere, or maybe it already exists in the firmware ?
I don't know how, so I duplicated it for now.
I or someone else will update this in a future PR.

BTW, you might need to check your beep frequencies to see if they still sound good after changing the sampling rate.

Yes, thanks I did it. It's bit less high, but not bad. Time will tell if we need to adjust the map, but it should be good for a start :-)
