I am starting to put together slides and PRs to preserve work of mine that lives offline before I leave.

The CRTBlob reconstruction aims to produce objects that represent the totality of all activity happening within a fcl-configurable coincidence window. They are similar to CRTTracks but without geometric track constraints, and as such can capture all activity from a single source, for example when multiple particles from the same air shower are detected or secondary particles are produced from the muon scattering.

It was used to produce a plot for the detector paper and is therefore worth preserving. It is not run by default in production fcls but does provide fcls for running it independently in the CRT-only workflow or standalone. Nothing prevents it being added to production fcls in future if it is desired for any analyses.

It is documented in slides: https://sbn-docdb.fnal.gov/cgi-bin/sso/ShowDocument?docid=45658
Accompanying PR: SBNSoftware/sbndcode#916
