Use js-tokens to reduce the size of this dependency

[sheremet-va]

Clear and concise description of the problem

This package uses acorn to parse JS code which is a bit large for the use case.

Suggested solution

I propose using js-tokens instead of acorn to reduce the size of this package. This package is used in Vite and Vitest that both had acorn in dependencies through rollup, but rollup stopped using acorn in the latest major version.

The package itself is much more lightweight, but it relies on a series of regexp manipulations. Still, as far as I understand, it correctly finds commends and multicomments.
