Sector Finder: Support for charged & neutral particles, added action function and validator

[rtysonCLAS12]

Before this pull request the config file was set up to take the same bank to find sector for charged and uncharged particles. This is problematic because the natural choice for charged particles (DC) is different from neutrals (calorimeters). SectorFinder also needed an action function and a validator

This pulls request introduces:

• Different banks for charged and neutral particles in config yaml. Choice is given to use default for one or both of charged/neutrals. Also fixed a bug due to certain banks containing non FD detectors, now only look at FD detectors.
• Add pindex entry to output bank to avoid confusion due to filtering of REC::Particle bank.
• Introduce a vector action function which finds the sector for a given pindex from a vector of sectors and pindices taken from some bank.
• Introduce a validator. This produces plots of the per sector X/Y calorimeter position for e- and photons. It is then trivial to see that the sector finding works as the X/Y positions are all in the right sectors. See below.

@c-dilks not sure why the CI is failing, sorry

looks like a transient pip problem; successful after retry

Let's also make the action function's docstring clear to a new user (who may not want to read the code example, which I think is clear enough).

Ok, thanks for the suggestions!

Ignore macOS CI failures, since the ROOT auto re-build over the weekend failed reproducibly.
