Add support for JBIG2 (generic coding)
...
Implements the proposal detailed at
#112 (comment)
This is a limited implementation of JBIG2, which can be extended to
support multiple pages, symbol tables, and other features of the format
in the future.
To test, I included a test fixture. You can also download 042.bmp (the same
one as @josch already downloaded in #112 (comment)
from https://git.ghostscript.com/?p=tests.git;a=blob_plain;f=jbig2/042.bmp;hb=HEAD
and run the following command:
jbig2 042.bmp | img2pdf > 042.pdf
This results in a small PDF, just as @josch originally found in the
comment mentioned above.
This is my first contribution to this repository so let me know if
something else is needed. Thanks for a great library!

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.

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.
