* Make ConvertToAst trait fallible It's got some panics, and we'll be switching those to errors! * First example of a diagnostic-driven error Add a diagnostic-driven error `#[wasm_bindgen]` being attached to public functions, and add some macros to boot to make it easier to generate errors! * Result-ify `src/parser.rs` This commit converts all of `src/parser.rs` away from panics to using `Diagnostic` instead. Along the way this adds a test case per changed `panic!`, ensuring that we don't regress in these areas!
