rust-index: use a `BitVec` instead of plain `Vec` for heads computation...

rust-index: use a `BitVec` instead of plain `Vec` for heads computation The `Vec` method uses one byte per revision, this uses 1 per 8 revisions, which improves our memory footprint. For large graphs (10+ millions), this can make a measurable difference server-side. I have seen no measurable impact on execution speed.
