user configurable sample rate, true peak detection

Browse source 
1. User can set sampling rate to suit expected range of frequencies:
- HIGH suits 4" or smaller and 6S 5"
- MEDIUM suits classic 5" 4S
- LOW is for 6" or greater
Limits automatically scaled:
HIGH : 133/166 to 1000Hz, MEDIUM : 89/111 to 666Hz, LOW : 67/83 to 500Hz
2. Bandpass entirely eliminated, not needed.
3. True peak detection method, favouring first peak to exceed 80% of maximum bin height; ignore or threshold values not required.
