Migrate to peggy

[Enteee]

          [Peggy](https://github.com/peggyjs/peggy) claims to be the successor for PEG.js with [backwards compatibility](https://github.com/peggyjs/peggy?tab=readme-ov-file#migrating-from-pegjs). at the time of writing the last commit to it was 4 days ago. would it be possible to migrate this parser to the more maintained dependency?
