Fix Excel date import - Fixes #1908 (#2909)

* Add utility functions to check/convert dates

* Add date tests and refactor to DRY up

* Fix date import - fixes #1908

Change from java.util.Date to OpenRefine 3.0+'s OffsetDateTime
Fixes #1908

* Centralize date conversion

* Moving utility methods to ParsingUtilities

* Fix tests
