Decode a ZeroLocus62 label

ZeroLocus62 is a compact format for ambient products, bundles, zero loci, and degeneracy loci of completely reducible bundles on partial flag varieties. Each label has an ambient part and, after the separator ., optional bundle data. Degeneracy loci use - to separate the two bundles and rank bound.

A one-bundle label is also a canonical description of the bundle itself, even when the bundle is not globally generated and no zero-locus interpretation is intended. For the full description of the encoding format, check the specification.

This decoder tracks the v3.1.1 reference release of the v3.1 format.
