67dc53df1f Acurite 592TXR Temperature/Humidity Sensor 
- Add support for 592TXR "Tower" temperature/humidity sensor
- Alternate 5n1 weather station shared device decode with 592TXR
- Wind direction decoding matches Aculink bridge and Acurite 1512 consoles
- More reliable decoding/detection with PWM_TERNARY demod (wider level range)
- Timestamps on 5n1 output
- Original 5n1 implementation left unchanged for compatibility

49647d09f9 Add support for new demodulation 
No level shift within the clock cycle translates to a logic 0
One level shift within the clock cycle translates to a logic 1
Each clock cycle begins with a level shift

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

f6fc204bbb Implement a PWM decoder with precise timing for increased selectivity 
Makes Chuango less noisy
Has provision for replacing ternary encoder (implements sync)
Can be expanded to include more selectivity (e.g. gap timing)
Can be expanded to include start bit removal (for replacing RAW)

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

9232c8dbc1 FSK: Complete the stack. Add stub drivers 
May still need some tweaking - but works for Danfoss.
E3CK has very small pulses! (~12) and should probably have higher
samplerate.

660cc2d40c Lower default level limit to 8000 
Max theoretical value is 16384 (values above is ripple due to
saturation). Decodes better signals with lower levels.
Analyses rtl_433_tests/tests/GT-WT-02/gfile003.data cleanly
