Add u-blox M7 Power mode setting UBX_CFG_PMS about stratux HOT 4 CLOSED

Not sure I am a fan of it. It is a setting that 99.9% of users will not understand and shouldn't touch anyway. We should find a reasonable default that works. What gave you the idea that it should be changed? Can you elaborate a bit?

After building many stratux with VK-162 USB dongle and testing them I noticed that commenting this line the time to fix and performance is much improved:

I suspect that this kind of M7 works better with default UBX_CFG_PMS

Surprising... But if that's really reproducible, than do that for all Ublox 7, not as a setting. I will conduct some tests tomorrow, too.

Just did some tests with an M8N.
Testing methodology:

• Plug GPS in, start Stratux process to get our basic configuration on it, and wait for a fix, just so things are warmed up.
• Stop Stratux and connect via U-Center
• Trigger "Coldstart" and measure time to first fix to collect samples
• After 5 samples collected, switch to "Balanced Mode" and collect again

Result samples(seconds):
Full power
47
47
88
59
53
-> Median: 53, AVG: 58,8

Balanced
51
54
50
53
30
-> Median: 51, AVG: 47,6

Admittedly, the sample size is not big, but I think we can safely say, that "Full Power" mode at least doesn't significantly improve anything.

Conclusion: We remove this setting entirely and use the default, assuming that the UBlox engineers know what they are doing.
