[TYT-9800] fix tone squelch (CTCSS Decode) not working #3007

As described in #3007, when channel tone mode set to TSQL (CTCSS Encode & Decode)
or DTCS (DCS), the squelch is being opened for any carrier, not just ones with specified tone.

Appears there is additional field in channel memory which specifies squelch mode, carrier or tone, which also needs to be explicitly set by Chirp whenever using TSQL or DTCS tone modes, as this is the intended behavior of these modes.
