Removing unused imports.

[thekevinbrown]

While I was working on #34, I noticed some imports that are unused. This PR removes them.

Note: Contribution guidelines say I need to make check, but that currently does this for me:

❯ make check
make: *** No rule to make target `check'.  Stop.

But I believe I'm following the coding style.

I also think I ran the tests...?

❯ npm test
npm ERR! Missing script: "test"
npm ERR! 
npm ERR! To see a list of scripts, run:
npm ERR!   npm run

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/kevin/.npm/_logs/2023-06-22T03_35_53_904Z-debug-0.log
❯ make test
make: `test' is up to date.

Definitely let me know if I need to do anything else here.

Thank you for this!
