[RFE] Mic calibration file support

[gaydenko]

It would be great to add mic calibration file support.

That would probably be a useful addition, although I don’t have access to calibrated mics. I’d have an idea how to do this in Matlab, but not in C++, so I’ll leave it just open.
Is there a canonical format for calibration files (for example, frequency and level values in an ASCII file)?

I added support for calibration files to: https://github.com/mincequi/qLouder
You can inspect my code to find out, how i did it.
