`ifd_maker_note` may raise error if exif_file.make is not set yet

There is a possibility that MakerNote section is in front of Make section, which will raise an exception as follows:

AttributeError: ExifSegment instance has no attribute 'make'

A possible workaround is just skip this section.

def ifd_maker_note(e, offset, exif_file, mode, data):
    try:
        exif_file.make
    except AttributeError:
        msg = "Haven't got make yet. Skipping."
        raise JpegFile.SkipTag(msg)

    # ...
end

I confirm the above fix works

It would be cool if this could be put on pypi.

But it is cool anyway that the fix is here to apply manually :)

Is anyone addressing this? I can confirm that christophlingg's code in commit https://github.com/komoot/pexif/commit/b6f42517c82a2c1c47c691e429129e722029ca7b works

Thanks for the fix, would be great to have this fix released. Meanwhile we have to :monkey: patch
