Observatory module with basic dome and weather handling created

Summary:
The Observatory module is a new EKOS module for handling all dome and weather devices. This initial implementation creates only basic functionality:

• Display weather information
• Park and unpark a dome
• Open and close a shutter
• Closing shutter / parking dome for weather status changes

Test Plan: Since everything has been developed with the INDI dome and weather simulators, it is of special importance testing the functionality against real hardware.
