DMR detector add

[autodiag]

it would be good to add DMR signal detection to the scanner for at least two reasons
1.in the case of scanning, it would not stop on the idling DMR networks

2.on the other hand, in case of scanning DMR networks it would be good if it would stop on the active network, find out if there is a call and if there is no call it would continue.

the actual decoding and all necessary features can be solved by a third party application in the standard way (virtial audio or TCP audio link) and it doesn't have to be a part of it because of the unclear license to AMBE, or it can be solved with the help of ambesticks etc etc...

I'm afraid until there's no shared library in gqrx, or at least sending audio signal via UDP, apparently there is 🤔 there's no way to hook into an actual signal other than hacking sound systems (alsa, pa, pw or whatever) (which it would be a tremendous amount of work). This scanner only takes advantage from remote control in gqrx which is... primitive to say the least.
