[chirp_devel] Starting work on Leixen VV-898S driver

An announcement of intentions: having just bought an 898S and being saddened that it's not supported, I'm working on a driver to support this model. I have the 3-power-levels change worked out, now I'm going through some of the other tweaks they made on this model.

I wanted to make sure I'm not stepping on any toes. Is anyone else working on an 898S driver?

My plan is to make a patch in the near term that gets basic support working equivalent to the 10w 898 model, then go back and add support for additional features like the VFO memories, DTFM sequences, etc.

Thanks, -- Brian AF7MD
