### New Features
- more efficient distribution of tasks to threads during pack resolution.
This clearly is a peak-performance optimization as it will now
efficiently distribut tree-root nodes to threads one at a time by
means of shared memory, which is accessed mutably yet safely.
This change can also further reduce peak memory usage as it will not
keep buffers of more resolved deltas then necessary, as it only handles
one at a time per thread.
### Bug Fixes
- reduce memory usage for pack resolution by 18%…
…compared to where it started out before.
This is the result of using u32 intead of usize where possible,
leveraging the object limit of u32 in packs.
This change makes the biggest difference by not keeping the decompressed
memory of leaf nodes alive for longer than needed, at the cost of
some code duplication which could be extracted into a function if one
was inclined to deal with the boilerplate and lots of generics.
- Allow verification of empty packs and indices.
Empty packs are fine, even though the implementation should probably
assure to not write them, or remove them after having been written.
- increase pack-receive performance using a BufWriter
Previously the NamedTempFile would receive every little write request
for millions of objects, consuming considerable amounts of time.
Now a buf writer alleviates this issue entirely.
- `bundle::write::Error` is now publicly available
### Bug Fixes (BREAKING)
- Reading and writing empty packs is explicitly allowed.
This can happen when sending packs that don't actually contain changes,
but need to be sent to conform to the protocol.
