Update parser, interpreter to Rust 2021 edition #72

While we're probably well past needing to support earlier versions of Rust, are there any specific reasons this project requires the 2021 edition in order to be used?

The usual things are that the feature resolver in cargo changed (and you already have the examples using 2021 edition). There were also a couple of additions to the prelude.

Rust 2021 edition was in 1.56 and the practical current msrv right now for this is 1.66 or so (regex needs 1.65, axum needs 1.66).
