Code Review

This pull request introduces optional support for the defmt logging framework, updates the README, and bumps the crate version to 0.2.3. A review comment points out that the defmt dependency version is set to a non-existent version (1.0) in Cargo.toml, which will cause build failures and prevent successful publication.

[gemini-code-assist]

The version bump to 0.2.3 appears to finalize the addition of defmt support. However, the defmt dependency version is currently set to 1.0 in Cargo.toml (line 49), which does not exist on crates.io (the latest version is 0.3.x). This will prevent users from using the feature and will likely cause issues during crate publication.
