Add bit removal methods to SparseBitMatrix and factor *BitSet relational methods into more extensible trait

I need the ability to clear the bits out of a row from `SparseBitMatrix`. Currently, all the mutating methods only allow insertion of bits, and there is no way to get access to the underlying data.

One approach is simply to make `ensure_row` public, since it grants `&mut` access to the underlying `HybridBitSet`. This PR adds the `pub` modifier. However, presumably this method was private for a reason, so I'm open to other designs. I would prefer general mutable access to the rows, because that way I can add many mutating operations (`clear`, `intersect`, etc.) without filing a PR each time :-)
