Investigate support for Haskell

[taybenlor]

Asterius https://github.com/tweag/asterius is an interesting option, but it appears to compile to its own JS ABI. Its also unclear if it will be possible to compile Asterius itself to Web Assembly.

It's likely that a better option would be to compile a Haskell interpreter.

There's also this set of tools https://github.com/WebGHC/wasm-cross (but more about compiling)

Asterius appears to now be deprecated with a new backend being merged into GHC: https://www.tweag.io/blog/2022-11-22-wasm-backend-merged-in-ghc/

GHC now has a wasm backend in https://www.tweag.io/blog/2022-11-22-wasm-backend-merged-in-ghc/
