[th9800] add tx inhibit feature per channel #2229

add tx inhibit feature by setting txfreq and offset to 0.
Causes RX to be normal, but when duplex=off, no TX and ERROR
displayed along with beep.

Note: Minor cosmetic side effect is that display indicates negative duplex
offset, probably because 0 is always < rxfreq. This may be unavoidable unless
we can find an actual channel flag which is designated for tx inhibit.

Also added channel field "reverse" to map.
