[Tetrapol-kit] new automatic channel detection tool

Hi,

in branch detector-01 is new tool with automated channel detection. It should not suffer the bug known from run.sh tool and should work with latest distribution GnuRadio.

This is preliminary version, it will be modified and refactored lot in future.

usage: - build tetrapol-kit using instructions from README - goto demod directory - edit tetrapol_detector.sh as needed (now set-up for rtl-sdr and 393MHz band) - run ./tetrapol_detector.sh (now takes 30 sec samples) - see results in demod/tmp directory (.log files)
