Build(deps): bump the minor-and-patch group with 2 updates

[dependabot]

Bumps the minor-and-patch group with 2 updates: redb and uuid.

Updates redb from 4.1.0 to 4.2.0

Release notes

Sourced from redb's releases.

4.2.0

New features

• Add an experimental cursor API, behind the experimental_cursor feature flag: Table::lower_bound_mut() and Table::upper_bound_mut() return a CursorMut pointing at a gap between entries, modeled on the standard library's BTreeMap cursors. Inserting sorted data through its insert_before() method can be around 3x faster than calling insert() with the same data; insert_after() inserts through the gap in descending order at the same speed. ReadableTable::lower_bound() and ReadableTable::upper_bound() return a read-only Cursor. The feature is unstable and may change incompatibly, or be removed, in any release.
• Add ReadOnlyTable::get_owned(), ReadOnlyTable::range_owned(), ReadOnlyMultimapTable::get_owned(), and ReadOnlyMultimapTable::range_owned(), which return the new OwnedAccessGuard, OwnedRange, OwnedMultimapValue, and OwnedMultimapRange types. These keep the read transaction alive until they are dropped, including the guards yielded by the iterators, which may outlive the iterator that produced them.
• Add Table::entry() and the associated Entry, OccupiedEntry, and VacantEntry types, mirroring std::collections::BTreeMap::entry. Supports or_insert, or_insert_with, or_insert_with_key, and_modify, and the usual OccupiedEntry / VacantEntry accessors.
• Add ExtractIf::close() to explicitly finalize an extract iterator without removing unread entries.

Optimizations

• Improve write performance: Durability::None commits are about 2x faster, and writes that do not split a page are about 15% faster for single-key Durability::None commits and about 6% faster for batched writes.
• Improve write performance when tables of a single WriteTransaction are modified concurrently from multiple threads. Writes to separate tables previously serialized on internal locks and could be slower than writing from a single thread; they now scale with the number of threads. Up to about 4x faster.
• Optimize Table::pop_first() and Table::pop_last() to be about 2x faster.
• Optimize inserting in ascending key order. A table loaded in key order occupies about half as much space, and loads faster.
• Optimize Table::retain(), Table::retain_in(), Table::extract_if(), and Table::extract_from_if(). Benchmarks on large tables show a 30-100x speedup for retaining and an 18-65x speedup for extracting, depending on the fraction of entries affected. Iterating an extract iterator from both ends no longer degrades removal batching.
• Avoid unnecessary write amplification when removing a value that is not present from a multimap table. Such a removal is now a no-op.

Minor improvements

• Table::retain(), Table::retain_in(), Table::extract_if(), and Table::extract_from_if() now poison the write transaction if their predicate panics or an internal error prevents removals from being applied, causing WriteTransaction::commit() to return CommitError::TransactionPoisoned. After an extract iterator returns an error, later calls keep returning an error instead of continuing.
• Enable file space reclamation during non-durable transactions performed while a savepoint exists.
• Reuse pages freed by a durable write transaction in the next write transaction when no live read transaction or savepoint still needs them. Previously, pages were not reused for one additional transaction.
