Should we rename the top-level package for the sdk from open_feature to openfeature?

The opentelemetry sdk does not use an underscore either, as is the case for most common Python packages which come from combined-word names (see matplotlib, numpy, pytorch, tensorflow)

This is of course a breaking change, but since we are revamping our whole package structure for this release, it's no more breaking than the rest of the changes that we are introducing.

I'm curious to hear your thoughts on this!
