Hi,

One of my co-developers asked me to look into using Divan and codespeed for running some of datafusion's benchmarks. I've been migrating a bunch of the Rust based ones to being sql based to make adding and modifying sql-type benchmarks easier to use. However I only have one entrypoint that doesn't really lend itself to a #[bench] annotation.

I've love to have the ability to register benchmark groups and entries programmatically in Divan rather than relying exclusively on the annotations.
