Bumps github.com/fxamacker/cbor/v2 from 2.9.4 to 2.9.6.

Release notes

Sourced from github.com/fxamacker/cbor/v2's releases.

v2.9.6 fixes 12 bugs, including an important fix for apps that decode CBOR maps into Go maps, and has one behavior change. API is unchanged but more errors are detected.

Most of these bugs were identified while improving tests and reviewing code for an upcoming release.

Tests and fuzz tests were extended.

Upgrading to v2.9.6 from all prior versions is recommended.

🐞 Important Fix

For use cases outside the "not affected by this bug" list below, decoding a CBOR null or undefined map key or value (including 55799(null)) into a Go map whose key or value type is of bool, integer, float, or string kind kept the previous map entry's key or value (instead of the zero value). See PR #855 for details.

Not affected by this bug:

• Decoding data this codec encoded from the same Go map type, because this codec does not encode to CBOR null from Go values of bool, integer, float, or string kind.
• Apps that don't decode a CBOR null or undefined map key or value into a Go map whose key or value type is of bool, integer, float, or string kind.
• Decoding CBOR maps into structs (struct fields of map type follow the bullet above).
• Decoding CBOR maps into map[any]any, and into any (with unchanged DefaultMapType).

⚠️ Behavior change

Decoding CBOR null or undefined into an interface that holds a value now sets it to nil, matching encoding/json (v1 and v2). Previously, the interface kept its value (PR #827), which was not the intended behavior.

🛠 Bug fixes

Some of these bugs could only be triggered by incorrect usage in user apps, such as invalid struct tags or an unsupported DefaultByteStringType setting, etc. None of these bugs were reported by a project affected by them.
