[Rust] Speed-up Unidecode librairy and learning exercise

[gmaOCR]

I’m currently learning Rust and working on improving the performance of Unidecode by rewriting the library in Rust.

I plan to use the pyO3 module so the library can still be used in Python, with minimal changes required. I will do my best to preserve the original function signatures, making it possible to simply change the import at the top of your Python files and immediately benefit from Rust’s execution speed.
Any help, guidance or test is welcome.

Thank you !
