Create new confparams token of 'ritclr' for clearing RIT/XIT offset
without turning off RIT/XIT function. Thanks to Tor, N4OGW, for the
request. May be replaced in the future by a dedicated RIT/XIT clear
function in the Hamlib API.
Implemented kenwood_cfg_params structure to allow RIT/XIT tokens to be
available to all Kenwood backend rigs (Fine Step and Voice announce are
also defined). K2/K3 rigs can only set/get RIT/XIT.
Updated README.k2/k3 for RIT/XIT functions and prior updates.
