Draft: Harmonize and document enums

Relates to #18

To be discussed:

• OSI defines all enums with UNKNOWN = 0 and OTHER = 1. We only do that on some enums.
• Fog has to be clarified. It seems to me that Visibility would be a more fitting name.
• Always explicitly define the first value as 0 and leave the following values unspecified?
• Always use type int or smallest possible type?

The program was tested solely for our own use cases, which might differ from yours.
