Previously the BNF types implemented the ToString trait. However the
rust convention is to implement fmt::Display instead because it covers
wider use cases and automatically implements the ToString trait as well.
Now the types support format as well as to_string.
Apologies also that is change is bundled with rustfmt changes. I could not get vscode to play nice with formatting.
