pmToWeyl -- convert a PieriMaps row-form tableau to a SchurFunctors WeylFilling

Description

PM tableaux and WeylFillings have the same data layout (rows weakly increasing). This is purely a relabel: pmToWeyl wraps a list of rows as a WeylFilling (interpreting it as a basis element of the divided-power module $K_\lambda V$), and weylToPM unwraps. The conversion is reversible.Requires the updated SchurFunctors package that exports weyl and WeylFilling.
