945b99df70 Change pulse data from unsigned to int to avoid undefined behaviour 
Thanks to zuckschwerdt for noticing this!

b22c0cd870 Pulse_analyzer: Terminate pulses to ensure EOP detection in demodulator 
Will now decode e.g. FSK pulses.

149c34c121 Pulse_detect: Make FSK demodulation more robust 
- Correct hysteresis error (positive instead of negative hysteresis :-)
- Only detect FSK at first pulse in possible OOK sequence

f24127c383 pulse_detect: Adding FSK demodulation 
First implementation with OOK/FSK package determination.
Based on adaptive quantization with frequency estimators.

7e6bbfafc1 Add pulse and gap level statistics 
Useful for determining signal and noise level.
Changed interval notation to mathematically correct notation [;]

9d1e6f5430 Pulse detector: added MIN and MAX gap time before EOP 
Implemented minimum and maximum gap times in addition to current
gap/pulse ratio. Changed values to be independent of sample rate.
Also made bitbuffer less noisy for decoders with small .long_limit

c59860eb36 Added generic pulse detector 
Initial attempt at making CPU efficient demodulation by making a common
data sample processing. The CPU intensive sample based demodulation will
be replaced by a common pulse detector outputting a pulse data structure
for further processing.
