After setting up a new SvelteKit project, adding the plugin (`@ianvs/prettier-plugin-sort-imports`), there's an error formatting some TS files:

1. Clone this repo — [gyenabubakar/prettier-import-sort-issue-repro](https://github.com/gyenabubakar/prettier-import-sort-issue-repro.git)
2. Install packages — `npm install`.
3. Format codebase — `npm run format`

**Expected behavior**

Should format the non-ignored files in the codebase without errors.

**Configuration File (cat .prettierrc, prettier.config.js, .prettier.js)**

Pull request:
Throw an error when no matching sortOrder group
Closes #190 

This adds a more understandable error message when we encounter an import that does not fit into any group within `sortOrder`.  I think the only time that should happen is when the user adds groups with `<TYPES>^.....` but no fallback `<TYPES>` bucket.  We could try to shove one in somewhere automatically like we do with `<THIRD_PARTY_MODULES>`, but that could be pretty confusing and I don't know where it should go in that case.  This also includes a hint about how to fix the error.
