Improve createFromStructuredData()

[kylekatarnls]

• Allow empty array for createFromStructuredData() (as specs allow it)
• Make OpeningHoursSpecificationParser constructor private and add separated named constructors
• Add details in exceptions to know what is the issue precisely and which item is incorrect
• Accept empty array as per specs for structured-data
• Add utils to know if opening-hours are always open/closed
• Add OpeningHours::every() method
• Make 23:59 short for 24:00 in createFromStructuredData (the way to represent 24h/24 for OpeningHours)
• Make range where closes < opens span over night (as per specs)

Hello @ambroisemaupate I made some changes to get a bit closer to specs such as allowing ranges over night by default. Implement 23:59 shortcut for end-of-day (not the same meaning as in OpeningHours class) and try to deal with invalid data with more verbose errors.

I also removed the check throwing exception when data is empty as it may be a valid case for some businesses and is allowed by the specs.

However I added a ->isAlwaysClosed() util so one can test after creation and throw an exception if it's not a valid case for the business.
