Add extension parameter handling for K2/K3 RIT/XIT

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.
