Fix hazardous default values for Power and SF for RFM95 even if I love the idea of SF255 :-)
Added #define option to offset battery voltage LIPO_OFFSET_MV (default disabled)
Sometimes R/R divider may not accurate and battery voltage can be shifted, so percent calculation may be wrong, this offset is added on each measure to fix it
Best way to know this one if to fully charge battery (should be 4.2V), and read on GPS screen battery voltage to view difference, in my case reading was 3950mV so added 250mV offset
It's empiric of course, not best but better than nothing
