Will Bainbridge d7ff97f490 lagrangian: Optimised reduced-dimension constraints

The 4.x tracking enforces reduced dimensionality on the parcels by
moving them to the centre of the mesh at the start of each track,
without considering the topology. This can leave the parcel outside it's
associated tetrahedron.

The barycentric algorithm isn't tolerant to incorrect topology, so
instead of changing position, it was written to track to the mesh
centre. This worked, but effectively doubled the number of tracking
calls. This additional cost has now been removed by absorbing the
constraint displacement into the existing motion track, so that the same
number of tracking steps are performed as before.
