Parse a MaStR Microsoft-AJAX date string ("/Date(1548979200000)/") into a Date.
The offset form "/Date(1548979200000+0100)/" is accepted too; its milliseconds
are UTC already, the offset only names the sender's zone. Returns null if the
string is not in that format or the value is outside the Date range.
