Try to leave the bandwidth of the rig untouched

Browse Source 
Hamlib conflates mode and bandwidth which sometimes make it impossible
to  change mode  without  forcing a  bandwidth change.   Unfortunately
Hamlib  has  no  bandwidth  value  that is  documented  to  leave  the
bandwidth as is, despite this being easy to implement. Many Hamlib rig
back ends do interpret RIG_PASSBAND_NORMAL as "don't explicitly change
the bandwidth".

Some rigs  like the  Tentec Jupiter  have a  widest bandwidth  of 8kHz
which is larger than desired for this application so the old behaviour
of setting the default wide bandwidth  is not very friendly. Also many
rig  back ends  in Hamlib  do not  do the  required bandwidth  setting
correctly due  to the CAT protocol  having no way of  discovering user
defined bandwidth allocations.

Merged from wsjtx-1.4 branch.
