[chirp_devel] tmode of "TSQL-R"

Thanks! As I said earlier, I'm a very new Ham, so this is exactly the sort
of stuff I don't know. I''ll modify the driver to handle TSQL-R from the
tmode field and handle PAGER as an extra.

The ft-4 does not appear to have a DTCS-R function, by that or any other
name, so implementing non-support should be easy :-)

If you wish to add me as a wiki editor, I can update the Tonemodes page.
