feat: ESM support

[berenddeboer]

Description

Currently cdk-nag cannot be used for ESM modules. As I'm using SST as opposed to CDK I get all these __filename not supported errors.

Use Case

I'm using SST to build a lot of my CDK stacks in order to be more productive while developing and debugging lambdas.

Proposed Solution

This could be fixed in the library with a polyfill or by switching to ESM instead of commonjs.

Thanks for reporting! I am in no means an expert in this area, but from my initial research it seems like switching to ESM is not an option as it would break CJS users (which I would assume is the vast majority of users).

I will have to do further research into an appropriate pollyfill for this use case. PRs and suggestions are welcome!
