[hpsdr] New version of Hermes VNA PC code available

[Phil Harman]

Hi Greg,

There is a small drift in all measurements over the first 15 mins - I
guess as the ADC warms up.

If you want to re-load a previous calibration file then its best to do the
calibration after the warm-up period and then save it.

If you need to take an immediate reading, without the warm-up period, then
do a calibration just before taking the reading.

The transmission dynamic range is currently 115dB but I'm still improving
the code.
