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. Before: ``` ❯ cargo run --package limbo --bin limbo database.db --output-mode pretty ... limbo> selet * from a; [2025-01-05T11:22:55Z ERROR sqlite3Parser] near "Token([115, 101, 108, 101, 116])": syntax error Parse error: near "selet": syntax error at (1, 6) ``` After: ``` ❯ cargo run --package limbo --bin limbo database.db --output-mode pretty ... limbo> selet * from a; [2025-01-05T12:25:52Z ERROR sqlite3Parser] near "Token([115, 101, 108, 101, 116])": syntax error × near "selet": syntax error at (1, 6) ╭──── 1 │ selet * from a · ▲ · ╰── syntax error ╰──── ```
