[vx510] Partial driver for Vertex VX-510. #719

I lost interest in finishing support for this radio, but anyone is welcome to
complete this driver if they want. Download and decode works, apart from a
stray byte at 0xC that I haven't found a good way to handle. It might be a
checksum, but I haven't determined the algorithm to check it. Upload is
untested and set_memory() is unimplemented. Nearly every byte of the img is
decoded, so this shouldn't be very difficult to complete if interested.
