Bump redb from 3.1.1 to 4.0.0

[dependabot]

Bumps redb from 3.1.1 to 4.0.0.

Release notes

Sourced from redb's releases.

4.0.0

• Implement Drop on AccessGuardMut and AccessGuardMutInPlace, which requires that these be dropped before the Table they borrow from. This fixes a critical bug where the accessor could outlive the Table, and be dropped after the transaction had already committed. This could cause data loss due to the data in the accessor being written out after the transaction had already completed.
• Remove Legacy type. To migrate off the Legacy type, use the Legacy type in the 3.x release and copy the data to a table with plain tuples, before upgrading to the 4.x release.

3.1.3

• Fix a data loss bug which can occur when the guard returned from Table::get_mut() is dropped after the transaction has been committed.
• Add a warning to Table::insert_reserve() indicating that it can cause data loss and recommending to upgrade to the 4.0.0 release.

3.1.2

• Reduce memory usage of open databases
