Build fails with error[E0635]: unknown feature proc_macro_span_shrink

[tmaklin]

Hi, I'm trying to build ggcat with rust 1.72.0-nightly (0ab38e95b 2023-07-03) but the build keeps failing with an error related to unknown features. I'm guessing this has something to do with the nightly issues mentioned in #27?

what is locked in the Cargo.lock file, run `cargo update` to use the new
version. This may also occur with an optional dependency that is not enabled.
