Branch ready for merging back to master

Tested with new devices on Raspberry Pi. All work OK

Added in support for other devices like control and monitor only

Added support for MIHO014 in line relay. ...

Tested in simulation

inner_times now correctly set on both interfaces. ...

Tested in simulation

Now passes and uses inner_times override to radio driver ...

MIHO008 white_light working in simulation
and the ENER002 still uses the older inner_times=8

Device.config is now Device.radio_config ...

This is to prevent confusion with get_config and get_radio_config

Clearly documented plan of steps to implement the change
