Devs please update specs - help users debug LimeSDR mini

Freq range etc still TBD:

Please add Freq. range in Tx for the various bands, and ca. power level in 50Ohm.
Freq. Range Rx - various bands, approximate NF / Sensitivity level.

As I mentioned previously this is basic info that should be easily available and would help people debug their LimeSDR-mini boards - I am having issue with mine : /
