Investigate compiling xh to WebAssembly

This could be useful if we decide to have an online playground like jqplay.

It seems WASI could be the perfect solution for us.

That being said:

• I have been able to compile reqwest into WASI yet.
• reqwest's blocking API is not available in WASM 😬.

Edit: WASI doesn't seem to support async/await currently so WASM would be the way to go.

Proof of concept: https://xh-playground.netlify.app/

crates + npm packages used

• wasmer-js.
• reqwest
• syntect
• jsonxf
