Rewrite core parts (e.g. basic html elements) to Rust

[paveldedik]

After some investigation it seems like a viable option to just rewrite core parts of the library to Rust using pyo3. This could significantly improve performance at least for HTML generation.

Hints

• Modules ludic.base, ludic.html and ludic.formating could be rewritten to Rust
• For type hints, we would define interface using pyi files
• Styles generation could also be written in Rust
• Mainly custom components (like the catalog) would still be written in python.
