Initial release of @prefresh/utils

@prefresh/utils@0.1.0

cleanup (#26)

Custom hooks!

• Added computeKey and register to the window payload
  • computeKey will calculate a hash for functional components and custom hooks this will allow you to derive the need for resetting state or not.
  • register is a noop that might be used later
• Added a third parameter to replaceComponent allowing the user to specify whether or not the stat has to be reset.
