Remove unused dependencies

[elm-review-bot]

Hello 👋!

I noticed there were unused dependencies in your package. Here is a pull request to remove them. After this gets merged, I recommend publishing a new release, unless you are working on something else in the meantime.

I found this issue using elm-review and the NoUnused.Dependencies rule from jfmengels/elm-review-unused. You can re-create my findings by running this command:

npx elm-review --template jfmengels/elm-review-unused/example --rules NoUnused.Dependencies

If you like these findings and want to find more dead code in your code, you can add elm-review to your project like this:

npx elm-review init --template jfmengels/elm-review-unused/example
# then to run it:
npx elm-review # reports problems
npx elm-review --fix # fixes the issue.

More information on how to get started in the elm-review documentation, and you can read more about how dead code removal is done using this tool.

This pull request was made automatically (by @MartinSStewart). You can tell me to stop making pull requests like this by writing "please stop".

Have a nice day!
