Mantarray-waveform-analysis

------------------

- Added Twitch Interval Irregularity metric to per twitch metrics sheet and aggregate metrics sheet.

------------------

- Fixed the out of bounds error present in h5 file due to the fix in the ``peak_detector`` which mitigated the TwoValleysInARow error.

------------------

- Fixed the directionality of the twitch depending on whether the data metrics in the pipeline template are magnetic or force metrics.

------------------

- Fixed TwoValleysInARowError present in h5 file due to ``peak_detector`` in which the second peak is taller than the second.

------------------

- Updated calculations to convert magnetic data to Force

------------------

- Added twitch contraction and relaxation velocity metrics to metric dicitonaries
