A repo to track and build Ogmios on ci.iog.io to populate https://cache.iog.io.
Currently, versions are specified manually in flake.nix, but this may be automated in the future.
We need it to be able to quickly recompile and experiment with different Ogmios versions.
Especially from within certain Dockerfiles, which start with an empty /nix/store, and therefore take a long time to compile.
