Want z position cut to be more liberal for reco tracks

[jdkio]

For reco tracks, we can't be sure the front/end of the reco track is the primary track. Like the reco track might be two particles, and the end of the track is mostly particle 2. But we want the true track position to point to the nearest matching z position of the "primary" particle that makes up the track, ie the one contributing the most true energy. So expand the cut so it will find the nearest true position regardless of distance.

Also expands the z cut in general for true position starting/ending at TMS/LAr so that we have more info. But I don't think we care if we're too far because we can use birth/death position for those particles

Approving.

May be useful to add a default value for max_z_dist in GetMomentumAtZ() so it defaults to behaving like the previous version.
