Title: Allow PooledDataVector construction using a given pool.

In R it's useful to be able to provide a predetermined pool, e.g. `x <- factor(1, 1:10)` where the levels are 1:10.

This is a modified constructor to allow for this, but please let me know if there is a better way.

The other PooledDataVector constructor could use this one, but would amount to an additional pass through `x`.
