Create Morphir Parsing Frontend

# Create Morphir Parsing Frontend

We want to make it easier to add new front-ends to Morphir. One way we are looking at doing this is by creating:

- A Morphir language dialect (we want to fork one of the tree-sitter parsers for either Elm or Gleam, I'm thinking Gleam)
- A Morphir AST
- A way to map other parsers onto the Morphir AST (for example, directly map Elm and/or Gleam onto Morphir)
- The AST should capture enough info to feed into the type inferencer.

## Tech

We can get "free" parsers by leveraging tree-sitter parsers. We want to explore using tree-sitter parsers as a frontend to parsing.
