[JS/TS] Option not to follow dynamic imports

[sutarmin]

I found this library while trying to understand why my app splits into chunks the way it does. It is quite helpful for the analysis already, but one thing I'm missing for chunk analysis particularly is ignoring (not following) dynamic imports. Is there a way to do it or, if not, is there a way to implement it?

This is not supported right now, but it should be easy to add. I can take a look at this soon, in the mean time, feel free to submit a PR, contributions are always welcome!
