Update for headsetcontrol v3

[Psykar]

Removes deprecated silent cli arg and uses json parsing instead.

If we don't want to go this far, then we should at least hide the deprecated argument text which is spamming my logs atm :D

See https://github.com/Sapd/HeadsetControl/releases/tag/3.0.0 for context

Idk if that's a common theme with other headsets but at least with my Corsaid Void showing the bat% instead of just Chg makes no sense and percentage should probably be hidden because the percentage is (likely) measure via voltage at output, which during charging can easily go up to 99% despite the actual battery being something like 3%.

I just checked and the software in windows does the same - it will never show percentage during charging, only once the charger is unplugged will it report the percentage again.

This worked before where when charging it would not show percentage, only Chg, so that would be regression and likely to be perceived as a bug.
