[Proposal]: System.String.RSplit

[mikeronayne]

This should behave exactly like the System.String.Split overloads that accept count, except we start counting delimiters from the right instead of the left.

Python exposes this as rsplit (tests showing behavior here). (Note that Python's maxsplit parameter has a bit different semantics than C#'s count.)

Alternatively, instead of adding a new RSplit method, I could see this also being implemented as a new StringSplitOptions.
