feat: add `ignore` option to ignore files from build

[Mikescops]

Fixes #67

This is an attempt to solve the issue #67 by adding a new option in pkg called ignore, it let's define regex paths that will avoid files matching them to be included in the final bundle.

Feel free to add comments and suggestions on how to improve the logic, I have included a simple test as a demo.

Please also update README.md to document the new setting

So (18.x, windows-latest) is still breaking on this thing, it's hitting my nerves.

But the (16.x, windows-latest) is failing on my new tests, probably due to paths with \
