[Elecraft] K3 PTT -- done!

This is exactly how PTT interacts with QSK and SEMI break-in when the latter
two are enabled.  When they are DIS-enabled, then PTT has 100% priority to
put the K3 in transmit state and remove it from transmit state, i.e., return
to receive state.

As explained above, the K3 does BOTH.
