Remove test-related structs from src/model.

[guidorice]

Thanks for making this crate, although I have not really used it yet, it def. could come in handy. I noticed there seems to be some leftover test-related structs (Dog and Flea) in model.rs.

Oops I missed the contribution guidelines but I seem them now. This PR probably does not affect the changelog.

@guidorice just to keep things tidy - would you be open to rebasing your changes to modify the commit message per the contribution guidelines? I'd think refactor is probably the most appropriate tag for your work here (conventional docs)

[guidorice]

Sure, will do! 👍

@JadedEvan please let me know if the PR looks OK now. Thanks

Looking good @guidorice - thanks for accommodating the changes! We've yanked codecov on this project since it wasn't adding much value, we can ignore those failures on this latest CI build.
