preferences. Moved custom types (as it seemed useful here and there) to
wfviewtypes.h. Let's use the wfviewtypes.h file for any kind of datatype

meter type and wfview will show you TX or RX audio depending upon if you
are transmitting or not. You can also select only TxAudio or RxAudio.
This is nice for looking at Tx audio levels prior to transmitting, for
example, or metering the radio's "monitor" audio while transmitting.
