Hub01 Shop Integration

Hey!

So, as I promised, I went ahead and built a **Rust implementation of the Hub01 Shop API Client** to make integrating with CatLauncher super easy. You can check it out here:

- **GitHub Repo:** [SrGnis/Hub01-Shop-API-libs](https://github.com/SrGnis/Hub01-Shop-API-libs)
- **Crates.io:** [hub01-client](https://crates.io/crates/hub01-client)

I also threw together a **POC TUI** to test everything out, it’s in the `rust-poc` branch if you wanna have a usage example take a look here:
[rust-poc branch](https://github.com/SrGnis/Hub01-Shop-API-libs/tree/rust-poc/rust_poc)

If you’ve got any questions jus tell me! 😊
