Keep/drop modifier node (khN, klN, dhN, dlN, and the kN
shorthand for khN).
Wraps a dice expression with keep highest/lowest or drop highest/lowest.
An omitted count defaults to 1, so 4d6kh is 4d6kh1. count is a full
sub-expression, so 4d6kh(1d2) is legal — and its dice are drawn before
the pool.
Chained modifiers (4d6kh3dl1) do not nest: the evaluator flattens the
chain and applies each spec independently to the same pool, unioning the
dropped sets, which is the Roll20 rule.
