Bumps [cbor2](https://github.com/agronholm/cbor2) from 5.8.0 to 5.9.0. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/agronholm/cbor2/releases";>cbor2's releases</a>.</em></p> <blockquote> <h2>5.9.0</h2> <ul> <li>Added the <code>max_depth</code> decoder parameter to limit the maximum allowed nesting level of containers, with a default value of 400 levels (CVE-2026-26209)</li> <li>Changed the default <code>read_size</code> from 4096 to 1 for backwards compatibility. The buffered reads introduced in 5.8.0 could cause issues when code needs to access the stream position after decoding. Users can opt-in to faster decoding by passing <code>read_size=4096</code> when they don't need to access the stream directly after decoding. Added a direct read path for <code>read_size=1</code> to avoid buffer management overhead. (<a href="https://redirect.github.com/agronholm/cbor2/pull/275";>#275</a>; PR by <a href="https://github.com/andreer";><code>@andreer</code></a>)</li> <li>Fixed C encoder not respecting string referencing when encoding string-type datetimes (tag 0) (<a href="https://redirect.github.com/agronholm/cbor2/issues/254";>#254</a>)</li> <li>Fixed a missed check for an exception in the C implementation of <code>CBOREncoder.encode_shared()</code> (<a href="https://redirect.github.com/agronholm/cbor2/issues/287";>#287</a>)</li> <li>Fixed two reference/memory leaks in the C extension's long string decoder (<a href="https://redirect.github.com/agronholm/cbor2/pull/290";>#290</a> PR by <a href="https://github.com/killiancowan82";><code>@killiancowan82</code></a>)</li> <li>Fixed C decoder ignoring the <code>str_errors</code> setting when decoding strings, and improved string decoding performance by using stack allocation for small strings and eliminating unnecessary conditionals. Benchmarks show 9-17% faster deserialization.
