Improve development experience by moving to a workspace (#410)

This allows IDE integration to work when the root of the repository is
opened. Prior to this change, a developer would have to open cargo-insta
to get code completion for that crate.

This also causes clippy to run on all crates, so this commit fixes a few
lints.
