Problem this feature will solve

The code is full or constants. I tried my best so far to avoid magic numbers, but there are still a few of them. Sometimes, magic numbers are extracted into well-named constants, but these constants have to be repeated across files, or fetched from one another creating an unwanted relationship.

Desired solution

Extract and document constants in a dedicated class.

Alternatives considered

Examples:

• 3600 appears multiple times, most of the time to convert decimal hours into seconds, or the opposite
• DAYS_PER_JULIAN_CENTURY, currently in Astronoby::Epoch while not completely related
• SECONDS_PER_HOUR, currently in Astronoby::Angle but probably necessary elsewhere
