[chirp_devel] [PATCH 0 of 2 ] Wouxun, write on frequency ranges

[Marco Filippi IZ3GME]

Thanks to Gary Errol N9PTC who asked me to allow writing and offers himself (and his own radios) for testing I thinks it's now safe to add it to daily builds.
I added a warning to let people know it could potentially brick radios even if Gary says it works.
The warning is on a separate patch so it'll be easier to remove it once we feel safe ;)
