Curies-rs

This adds a small fix to the initial release to include metadata that was missing from Cargo.toml (specifically, wiring the metadata for the description to get reused for the rust crate)

This is the first development release of curies.rs. It includes two main data structures: Record and Converter. It has I/O operations to load up external extended prefix maps, JSON-LD contexts, and simple prefix maps. It also has an initial implementation of the converter chaining operation. It also has compress, expand, and validation operations for CURIEs and URIs.

> [!WARNING]
> The API will change before the next release.
