Regression test for the bug described in:
https://github.com/Exiv2/exiv2/issues/853
The date parsing code in XMPUtils::ConvertToDate does not
check that the month and day are in bounds. This can cause a
denial of service in AdjustTimeOverflow because it adjusts
out-of-bounds days in a loop that subtracts one month per
iteration.
