Ability to Manage Custom Commute Methods

**Is your feature request related to a problem? Please describe.**
The Commute Method selector in the visit form uses local storage to store its options (see `usePersistentState` hook), but has no way of modifying them after creating custom options.

**Describe the solution you'd like**
Replace the default Option component for `CreateSelect` with a custom one with an X button on the right so options can be deleted.

**Describe alternatives you've considered**
Something on the profile page to manage them is also possible if you can keep it consistent with the design.

**Additional context**
This issue might be harder simply because the react select docs are hell.
