It looks like I came to this same conclusion in #17, but now there is a PR up in upstream Rust, so I'll keep this open. |

This commit does everything except add the `const` annotation to the function signature. Adding `const` is blocked on rust-lang/rust#79549. See #49.

Rust 1.52.0 stabilized several char ASCII methods as const which are required by `lookup` if we wish to make `lookup` const. https://blog.rust-lang.org/2021/05/06/Rust-1.52.0.html#stabilized-apis This commit adds a job to the CI GitHub Actions workflow to test foccacia with the declared MSRV of 1.52.0. Due to several panics in incremental compilation in Rust 1.52.0, this job sets the `CARGO_INCREMENTAL` env variable to 0 to disable incremental compilation.
