Update for Inkscape 1.0.

- Adjust to changed export command line options of Inkscape.
- Fix TypeError on Python 3.
- Use the new file chooser support in the extension dialog.

Making it an output extension instead of an effect to skip the unnecessary dialog is still not feasible because Inkscape still buffers the whole output in a continuously reallocated string instead of streaming it to disk.
