I noticed that the parse errors were a bit hard to read - only the nearest token and the line/col offsets were printed. I made a first attempt at improving the errors using [miette](https://github.com/zkat/miette). - Added derive for `miette::Diagnostic` to both the parser's error type and LimboError. - Added miette dependency to both sqlite3_parser and core. The `fancy` feature is only enabled for CLI. Some future improvements that can be made further: - Add spans to AST nodes so that errors can better point to the correct token. See upstream issue: https://github.com/gwenn/lemon-rs/issues/33 - Construct more errors with offset information. I noticed that most parser errors are constructed with `None` as the offset. Comparisons.
