Bug Report Checklist

• I have tried restarting my IDE and the issue persists.
• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Expected

This package is mostly a collection of small functions and the occasional larger piece of analysis. It shouldn't be very large in output bundles.

Per https://pkg-size.dev/tsutils?no-peers, the predecessor tsutils was only 382KB in total.

Actual

Per https://pkg-size.dev/ts-api-utils?no-peers, it's 1.2MB. 😬

Additional Info

This was prompted by @ArnaudBarre noting in ArnaudBarre/eslint-plugin-react-refresh#62 (comment) a desire to have nicely typed rule options for a plugin without many megabytes of added dependencies. Thanks for the prod @ArnaudBarre!
