Found a problem with Flex which is fixed by changing the rig polling

Doing a profile change on Flex can take almost 3 seconds.
So if you have polling at 1 second WSJT-X times out waiting for the
profile change and actually requests hamlib to disconnect *(i.e.
shutdown).
This may explain random disconnects when any rig takes too long to
respond on any command.
There are a few possible solutions which I'll rank in my preference
order....
#1 Fix the polling to provide a fixed timeout of 4 seconds. Users
won't have any idea what to set for this and I don't see any problem
with waiting up to 4 seconds when things are getting delayed.
Normally we don't run into this timeout but we need to gracefully
recover when we do.
#2 Provide a user-controllable setting which defaults to 4 seconds.
Just in case this longer timeout causes a different problem. Maybe
put it in the release candidate and then remove it when nobody complains.
So...for Flex users....change polling to 3 seconds and use this
hamlib_settings.json file in the WSJT-X configuration directory
This changes will be in the next version of WSJT-X for the Flex6xxx entry.

Hi Mike,
please explain what you mean by requests Hamlib to disconnect? Are you
referring to a TCP/IP connection failure? Does this cause WSJT-X to
offer a Retry/Reconfigure/Cancel message box?
A 3 s polling interval being enforced is not acceptable for an issue
that only happens when a profile is changed on SmartSDR.
