For the future playground for the Ezno type checker: https://github.com/kaleidawave/ezno/pull/115

Can save an id for a content and recall content from an id (thus acting as a sort of compressor)

Inspired by how the https://play.rust-lang.org/ shares playgrounds. (However uses a SQL-lite db hosted by Valtown rather than GitHub gists)
