Update repo and misc changes

[wtgee]

• Updating the pyscaffold project setup for consistency with other repositories.
• Updating the dependencies to support panoptes-utils>=0.2.38.
• Changing to use markdown docs instead of rst for ease of update.
• Add from_altaz to Field class for easy creation.
• A bunch of to_value -> get_quantity_value changes for consistency.
• Compound observation can be created from_dict.
• Misc. small cleanup.
• Skip some astrohaven dome simulator tests because the serial protocol handlers were removed from panoptes-utils==0.2.37.
• Changes the docs to match the theme of panoptes-utils.

I'm having trouble with getting a good report from codecov. This probably decreases coverage some but is needed for updates.
