[Bug?] Mass recalibration does not constrain mass error. #143

Description

@jspaezp

I need to make more clear this message ... since we calibrate mz based on an offset + calculated error to set the second extraction tolerance its hard to say what it is here. (also the error message does not break down MS1 and MS2 ..)

Phase 2: Calibrate ....... WARN timsseek::processing::calibration: derived m/z window exceeded the first-pass window (15.0, 15.0) ppm; clamped. Residual MAD 4.2 ppm is contamination of the box-mean offset, not the instrument.

Probably the fix is to make a more elegant estimation of the error ... (rather than a mean fit a histogram and some form of density estimation fit ... maybe ...)
