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.
