cl-frontend: Improve the line-editing capabilities in REPL mode.
...
- Note: This adds a dependency on Crossterm, to set the terminal into raw mode. This could be eliminated by linking the libraries Crossterm uses directly... Or I could embrace Crossterm, and use it for all escape sequences in the terminal, instead of assuming DEC VT500 compatibility.

...
- Rewrote the grammar

cl 0.0.2: MAJOR ERGONOMIC BOOST
...
Broke frontend into its own library, "cl-frontend"
- Frontend is pretty :D
- Included sample fibonacci implementation
Deprecated conlang::ast::Visitor in favor of bespoke traits
- Rust traits are super cool.
- The Interpreter is currently undergoing a major rewrite
Added preliminary type-path support to the parser
- Currently incomplete: type paths must end in Never..?
Pretty printer is now even prettier
- conlang::ast now exports all relevant AST nodes, since there are no namespace collisions any more
