Remove github.com/lunny/log as a dependency from genbank.go

[ethanholz]

Describe the desired feature/enhancement

I would love to see github.com/lunny/log (which is now archived), to be replaced by Go's support for log/slog. This also would enable much better structured logging support.

Is your feature request related to a problem?

Not exactly, but it is an inconsistency in the codebase.

Describe the solution you'd like

Remove the dependency and replace with log/slog. Since we are already testing on Go 1.21, this should be okay.

Describe alternatives you've considered (optional)

n/a
