Dtw algo (#9)

* feat: implement Dynamic Time Warping (DTW) functionality

- Added DTW distance computation and optimal warping path functions in Rust.
- Introduced corresponding Python bindings for DTW, DTW_DISTANCE, and BATCH_DTW.
- Enhanced WASM support with a new dtw_distance function.
- Included comprehensive unit tests for DTW functionality, validating against the dtaidistance library and ensuring mathematical properties.

* chore: update ferro-ta version to 1.1.4

- Bumped version number of ferro-ta to 1.1.4 in uv.lock and Cargo.lock files.
- Ensured consistency across package dependencies for the updated version.
