Split cli and lib somehow

[epage]

For anyone using the library, they have to pull in clap, env_logger, etc.

Options

• Separate packages
• clifeature (on or off by default)

See also https://blog.rust-lang.org/inside-rust/2024/02/13/this-development-cycle-in-cargo-1-77/#when-to-use-packages-or-workspaces which discusses some of the trade offs

For context, I noticed this when reading a blog post complaining about dependency counts and tried to reproduce their setup.
