Optimize performance using web assembly

[Max98]

Web assembly allows us to run code natively on the browser => native performance
It supports many languages such as C/C++ etc, but i'm interested in Rust here. (up for discussion)
We can use this to offload all the computational functions to native code for much faster performance while editing, and keep typescript for UI and small stuff.

The switch from Electron to Tauri is one step toward this goal, Tauri supports Rust out of the box.
