✨🧪♻️➕ vanth, vanth_derive: Add derive macro for Vanth trait implementation

- Added `vanth_derive` crate with a procedural macro to automatically implement the `Vanth` trait for structs, including generics.
- Refactored `vanth` crate by removing obsolete `vanth.rs` file.
- Implemented `PartialEq` for `Ty` to enable comparisons with string values and another `Ty`.
- Added integration tests for deriving `Vanth` with generic parameters.
- Updated dependencies: added `quote`, `syn`, and `proc-macro2` crates.
