BREAKING CHANGE: the JSON format has deeply changed to enhance its
consistency

BREAKING CHANGE: the --day, --month and --year arguments have been removed in the
favor of a single one.

BREAKING CHANGE: invoking kosmorro command without --latitude and
--longitude arguments will now only output the Moon phase and,
eventually, the events for the given date (or today if date not given).

BREAKING CHANGE: JSON format now returns the moon phase as an object
instead of a string
