Validates the index for lookup values to prevent referencing random memory. Also validates the range of numeric parameters.
diff output will clearly show any corrupted parameters.
4.0 seems like a good time to rename these confusing legacy parameters to something that matches their function.
p_level -> angle_level_strength
i_level -> horizon_level_strength
d_level -> horizon_transition
Officially Invensense lists the experimentl mode as "unsupported" on the MPU60x0 series. Previously it was added to allow testing. It's been determined that it's not a viable gyro filtering operational mode.
Also change "experimental" DLPF support available for F4 or higher. Few F3 boards have gyros that can use this mode anyway. Saves 200 bytes.

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.
Improves on earlier 3.5RC1 dynamic filter with:
- better FFT tracking performance overall, even with a narrower default notch width
- can reach 850Hz for high kV 2.5-3" and 6S quads
- works better with 32k gyros
- can be applied pre- (location 1) and post- (location 2) static filters. Pre-static filter location works best, but post-static may work well in 32k modes or with PT1 option
- option to use a PT1 filter rather than the classical notch filter, perhaps useful for quads with a lot of noise above their peak.
- ability to totally bypass the pre-FFT bandpass filter, by setting Q=0, maximising the range of responsiveness
- "ignore" value, absolute FFT bin amplitude below which the bin will be excluded from consideration. May be tweaked to optimise peak detection; primarily for advanced tuners. If too high, only the very peaks will be included, if too low, noise may clutter peak detection.
- "threshold" value for peak detection, which, when divided by 10, is the multiple by which one bin must exceed the previous one for peak detection to commence. If too low, FFT detection becomes more random, if too high, no peaks are detected.
Harmonized (and partly corrected) all occurancies of gpsSol.llh.alt and getEstimatedAltitude() to handle altiude sourced in cm resolution.
This was introduced by GSP_RESCUE/RTH.
Introduced a naming convention that include the unit into the variable/function names:
gpsSol.llh.alt -> gpsSol.llh.alt_cm
getEstimatedAltitude() -> getEstimatedAltitude_cm()
