First pass at RF test board to evaluate quality and performance of
RF component placement.

To be connected directly to VNA for S11 (and S12 in the case of u.FL connector.)
Can also be used with signnal generator to estimate antenna radiation pattern.
Minor twak of SMA position.
Remove thermals on bottom layer.
