feat: WebAssembly support and JS version as bindings

[Alex Godoy Wolff]

Hello! Thank you for the amazing work on libphonenumber. Since the project already supports JavaScript, have you considered moving towards a WebAssembly (WASM) core, with the JS version acting as bindings? This would make the library much more interoperable across different platforms and languages, and could potentially improve performance and maintainability.

Are there any plans or discussions regarding WASM support in the future?

Thanks
