5100507403 Address discrepancies between PDF and XMP timestamps
The PDF format and XMP metadata specs define different syntax for dates,
so account for these discrepancies by more carefully constructing the
final timestamps by post-processing strftime() output.

1dd05cc36b Treat default creation/mod dates as UTC (fixes #155)
(Tested with Python 3.11.3 on Arch Linux.)

Without passing a tzinfo object to `datetime.now()`, a "naive" datetime
object is created, which is not timezone-aware. To fix the default
date/time detection for non-UTC local timezones, pass
`datetime.timezone.utc` to convert the value to UTC and make the
datetime object "aware".

Also, adjust the strftime() wrappers to use the UTC offsets instead of a
literal `Z`; using the literal `Z` at the end appears to be valid for
ISO 8601, but for some reason it does not successfully convert, whereas
the `%z` placeholder substitutes the UTC offset and successfully
converts.

Remove outdated readme entry concerning JP2 colorspace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.
