Use native fs - Githubissues

[x] Drop fsPath and use native node fs functions
[x] Update change log and bump as minor release

fsPath has a known vulnerability and had no updates from a long time. This PR will revert the dependency added to fix recursive writes while updating the call with the native functions.

Note that this requires a node version > 11.5 where these asynchronous functions where introduced. Set as >=12 to use the LTS versions.

I don't think this breaks backward compatibility but does require a newer version of node.

Testing

I ran the existing tests and it worked. I didn't expect the image to have a different md5, but there wasn't actually a image to start.

On my own tests, it was successful in creating recursively many directories and replacing the target.
