81502f21af Convert creation/modification dates to UTC (fixes #155) 
Ensure that timezones are correctly interpreted in the input by calling
`.astimezone()` as appropriate on datetime objects, and store the
resulting date fields as UTC.

One could argue that datetimes in the local timezone be stored in the
PDF, but then the date string handling becomes more complicated; the PDF
and XMP date specs both use the `Z` suffix to indicate UTC time, but
other +/- offsets require different syntax between the two specs.

Remove outdated readme entry concerning JP2 colorspace 
If I understood the code in `jp2.py` correctly, this should now work.
Moreover, Pillow should usually be able to open JP2 files, so `jp2.py` is only a fallback.
