0.4.0

• Updated Kotlin version to 1.3.0
• Fixed issue where multiple simultaneous calls to permissions request, calls permissions granted callback immediately (However, you should never do that) (Fixes #5)
• Fixed issue where permissionsDenied method was not called when handling the rationale and permanently denied were set to false (Fixes #6)
• Added logging warning messages when somethings you should not be doing. Like, calling cancel() / proceed() on request object from the permissions denied callback is not allowed. As the flow is already complete. However from the rationale or permanently denied callback, it is always allowed.
