NeewerLite-Python 0.6b

This release is a bugfix for 0.6 - the HTTP server implementation didn't let more than one Bleak call go through on Linux installations (both Ubuntu and Raspberry Pi OS/Raspbian had the issue) - so the asyncio call was moved to the top of the HTTP server and only called once (which is a better way of doing it anyway) - also, quitting out of the HTTP server now manually unlinks from each light. Neither Windows or MacOS had these issues (or their Bleak implementation just disconnected differently), so now everything should be good on Linux as well.
