[Feature Request] Allow us to adjust min num of satellites for GPS

[ramiss]

Describe the solution you'd like

Would be nice if we could set the minimum number of satellites for the script to think we have a lock. 6 is not recommended and I usually set at least 7 in BF, but to have my TX call out GPS Ready prematurely is frustrating.

Describe alternatives you've considered

Adjusting BF min sats down to 6, but that isn't as accurate.
