Briefly, what does this PR introduce?

Adds an algorithm which recovers the PID of particles detected in certain directions. The Low-Q2 electrons are the only charged particles which can be reconstructed within ~12mrad of the negative z-axis, currently this information isn't included in reconstructed particles.

The same approach could to a certain degree be used for the Far-Forward protons.

This is a temporary alternative to pursing the larger changes required by #1571 where the reconstructed particles from the tagger would come from a different collection.
