Make WASM optional to use the website

[p2-b]

It is essential that the web application should be able to function without WebAssembly. A project of this scope should not have this mandatory requirement.

As you can see in the following screenshot, wallet.brume.money page when accessed from Firefox without WASM:

WebAssembly increases the attack surface of any browser that supports it. You will find more info about it here: https://github.com/stevespringett/disable-webassembly

Hmmmm in our case most of the negative points from the link don't apply, because all our HTML/CSS/JS/WASM code is reproducible, is sent via encrypted transport (unless self-hosting), and is immutably cached, even more, all our WASM code has extra protection against tampering via a GitHub bot that checks that the bytecode matches, that means if someones doesn't trust our WASM code he should not trust our JS code either

Anyway, for compatibility purpose, I will try to add a fallback JS implementation for all WASM code
