Function Mocker Christmas update

While Christmas is almost on me I fix another issue with Function Mocker.

What’s to wrap, what’s not

I had previously walked the path of excluding from the wrapping any package in the vendor folder while trying to come up with a solution to function-mocker wrapping the wrong things.
Leveraging the exclude and include options, see the project README, and some smarter defaults I could make the wrapping work in all the projects I’m using function-mocker into.

The update is on GitHub, merry Christmas.
