mathlib: AlphaFilter add additional checks and updates methods
- setParameters() and setCutoffFreq() sanity check all input
 - on invalid configuration disable filter and leave in safe state
 - constrain cutoff frequency to Nyquist rather than disabling the filter
 - allow configuring only time constant directly
 - add new update() method with dt that also recomputes parameters if necessary
 - filter update don't allow invalid data (NAN, etc) to propagate
