Module selector 

The run length backed representation of a RowSelection: RowSelector and the primitives operating on a sequence of them.

This is the counterpart of the bitmap backing in the boolean module, and provides the same set of transforms (split_off, trim, offset, limit) over Vec<RowSelector> instead of a BooleanBuffer.
