IC-7300 (and other rigs besides Icoms) are doing unnecessary VFO swapping.
Also Icom rigs are not properly setting VFOB unless set_vfo is called first.

#1 Reduce Icom swapping in hamlib
#2 Fix Icom set_vfo to use 0x25 command for set_freq
#3 Add RIG_TARGETABLE_VFO_NOSETNEEDED flag to rig caps targetable_vfo so clients can recognize hamlib does not need them to set vfo to change freq or mode. This is necessary to allow backwards compatibility for old hamlib which needed the set_vfo and will be in shared libraries.
#4 Add VFO_RX/VFO_TX capability so clients do not have to know about VFO at all or split mode or reverse split.
