End time earlier than start time considered not valid

[westnordost]

A time span like 22:00-05:00 is not considered valid in strict mode, even though

• it is described as valid in the specification and

• this parser itself pretty-prints 22:00-29:00 as 22:00-05:00. (So, it currently creates strings that itself considers invalid)

As I previously pointed out https://github.com/simonpoole/OpeningHoursParser/issues/80#issuecomment-1881145178, mentioned in the README and in the JavaDoc https://github.com/simonpoole/OpeningHoursParser/blob/master/src/main/java/ch/poole/openinghoursparser/OpeningHoursParser.jj#L79 the behaviour wrt times is configurable.
