This implements:
- Crystal morphisms (usual, twisted, and virtual).
- Subcrystals, so we no long have to do the subset workaround in
`digraph()`.
- Virtual crystals, so we can now view the elements in the virtual crystal
as a crystal graph.
This also reworks `DirectSumOfCrystals` and `TensorProductOfCrystals` to
make them associative as constructions.
After this, we will be able to do coercions between crystals.
