maxWeylFilling -- the lex-largest Weyl-standard tableau of given shape

Description

With $p' = (p'_1, \ldots, p'_{p_1})$ the conjugate of $p$, the cell $(i, j)$ (0-indexed) is filled with $d - p'_j + i$. This coincides numerically with the formula for the lex-largest semistandard tableau on the Schur side (the internal helper maxFilling), but stored row-wise.

Useful as a starting point for constructing extreme elements of highest-weight subrepresentations; see characterRep and decomposeRep.
