v0.15.0

PyPI package: https://pypi.org/project/python-redux/0.15.0

Changes:

• refactor(autorun)!: setting initial_run option of autorun to False used to
  make the autorun simply not call the function on initialization, now it makes
  sure the function is not called until the selector's value actually changes
• feat(autorun): add auto_call and reactive options to autorun to control whether
  the autorun should call the function automatically when the comparator's value
  changes and whether it shouldn't automatically call it but yet register a change
  so that when it is manually called the next time, it will call the function.
