Rust 1.78 Clippy Warnings

[ctm]

Fix the clippy warnings that are appearing now that rust 1.78 is out.

I don't think I can turn off the #[wasm_bindgen] complaints. Looks like this is fixed in nightly, but slipped into stable. It's been reported in wasm-bindgen.

All the ones I can fix, I have fixed. I'm going to run a local smoke test and then run all the tests before deploying.

Deploying.

FWIW, the wasm_bindgen warnings go away with Rust 1.79, which comes out in a couple of days.
