Bump sled from 0.26.3 to 0.31.0

[dependabot-preview]

Bumps sled from 0.26.3 to 0.31.0.

Release notes

Sourced from sled's releases.

varints, read and recovery optimizations

0.31

Improvements

• #947 dramatic read and recovery optimizations
• #921 reduced the reliance on locks while performing multithreaded IO on windows.
• #928 use sync_file_range on linux instead of a full fsync for most writes.
• #946 io_uring support changed to the rio crate
• #939 reduced memory consumption during zstd decompression

Breaking Changes

• #927 use SQLite-style varints for serializing u64. This dramatically reduces the written bytes for databases that store small keys and values.
• #943 use varints for most of the fields in message headers, causing an additional large space reduction. combined with #927, these changes reduce bytes written by 68% for workloads writing small items.

sled::open replaces sled::Db::open

New Features

• Added the open function for quickly opening a database at a path with default configuration.

new storage format and bugfixes

• much faster compile speeds after aggressive dependency pruning
• new storage format
• bugfixes in cache invalidation and combining transactions with compression

Config, Transaction, and Opening Revamp

New Features

• The Config::open method has been added to give Config a similar feel to std's fs::OpenOptions. The Config::build and Db::start methods are now deprecated in favor of calling Config::open directly
• A checksum method has been added to Tree and Db for use in verifying backups and migrations.
• Transactions may now involve up to 69 different tables. Nice.
• The TransactionError::Abort variant has had a generic member added that can be returned
