JP-3737: Handle micrometeorite flashes

[drlaw1558]

This PR addresses JP-3737 by adding an additional check in the jump step to look for micrometeorite flashes, which manifest as bursts of jumps across a large fraction of the detector.

Kept in draft form for now pending potential future modifications.

Things that remain to be determined:

• Check that this function successfully detects more example flashes from the FGS list
• Determine whether it needs to be restricted in any way, e.g. to only FULL array or non-TSO data
• Determine whether to set mmflashfrac=1.0 by default (i.e., step disabled unless explicitly enabled by param ref file), or to set mmflashfrac=0.1 (for example) to explicitly enable by default unless disabled by param ref file.

Work ongoing to determine these.
