Setup clippy lints

[randomPoison]

We should make use of Clippy for static analysis in the project. This will likely take some minor setup:

• Clear out any existing warnings/errors it highlights.
• Configure warning levels based on our needs. For example, we likely want to disable complexity warnings.
• Setup Clippy to run as part of continuous integration. We'll likely want it to run as the last step that way we catch more important errors first.
