DuckDB allows underscores in numeric literals, e.g. 1_000_000. This PR adds support for this.

  • Add numberRegex option to TokenizerOptions to allow custom number patterns
  • Update Tokenizer to use custom number regex when provided
  • Configure DuckDB formatter to support underscore separators in numbers
  • Add test for underscore numeric literals in DuckDB

Let me know if you'd rather see this done differently! Thanks for the great library.

Thanks for the PR. Actually PostgreSQL supports the same syntax. Will make it work for both.
