-----------------------------+------------------------------------
The code for computing the crystal of LS paths takes a significant amount
of time reconstructing the family returned by `alphacheck` in the
corresponding root system. The proposal is to cache this (which is
consistent with what we do for other such functions for root systems,
e.g., `simple_roots`). This branch also does some other micro-
optimizations which results in about an additional ~5% speedup.
