feat: add cache @link{https://nodejs.org/api/modules.html#caching}

[GrinZero]

Increasing result caching to reuse running results - but this may not be an excellent solution, and we still need more practice.

Thanks for the PR! Since this is just caching the whole resolve() call, I think this is better solved in your application code. Caching might not be the right answer for all users. For example, what happens if I use resolve() in a long-running process, and the files on disk change? If the result is cached by the crate then you would not be able to react to changes until you restart the whole process.
