Examples requirement unnecessary for small packages

We maintain a small package called fluri (https://pub.dev/packages/fluri) that is currently being docked 10 points for not maintaining an example in the `example/` directory. This package's functionality is very small and for that reason, we've included usage examples directly in the readme. In fact, at this point, the description + examples make up the entirety of the readme.

It seems unnecessary to me that we would have to either duplicate or move the examples to the `example/` dir just to get those 10 points back, and I would argue that the readme is a better place for that information in this case since it is immediately accessible and explains the purpose of the package at the same time.
