[hpsdr] data acquisition option for PowerSDR mRX PS v3.2.7.0

[Georg Prinz]

Hello Joe,

this is super! I was looking for these capabilities, when I tested my
dish last year. As soon as the weather calms down in spring time, I will
give it a try.

Data is written to file (in real time if you like, as you are acquiring it) in plain text, .csv format, which Excel and other spreadsheet programs can import directly.
