Add Support for GHC

[heinrich26]

This may be quite the exquisite request, but in order to compile "Pandoc", the document-converter, one needs Haskell (and its package-manager cabal).

At least on PC, Haskell is quite the large package, so I don't think it should be included in the app by default.

To make it easier, Haskell has a Web-Assembly compiler version: https://gitlab.haskell.org/ghc/wasi-sdk https://gitlab.haskell.org/ghc/wasi-libc https://gitlab.haskell.org/ghc/libffi-wasm

My hope is to compile "Pandoc" with that, to be included in the project.
