Another set of changes that I had held back because it was based on other changes that weren’t merged at the time…
Do not crash when a tuner is selected in the dialog but libdir is not found
Exit cleanly when the SDR driver is not found
Support both NativeTunerGroupReader and SdrGroupReader selection in GUI (will first try NativeTunerGroupReader, then SdrGroupReader if the former is not available)
Behave gracefully when the user closes the selection dialog without making a choice
