do not include thumbnails in the output by default unless --include-thumbnails is used
This is relevant for the MPO format which otherwise would result in PDF
files containing the same image in different sizes multiple times. With
this change, the default is to only have a single page containing the
full MPO. This means that extracting that MPO also gets the thumbnails
back.

With the --include-thumbnails option, each frame gets stored on its own
page as it is done for multi-frame GIF, for example.

Closes: #135

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.
