Add 'pseudonymise' option

[sal-uva]

Feature request to have an option to pseudonymise data when uploading to 4CAT. This is of course already possible within 4CAT, but I'd argue it makes sense to have within Zeeschuimer as well, knowing people stick with the defaults and in light of the potentially personal/private data collected.

Could be done through an API call to start the pseudonymise processor right after a successful upload.

That would be the method, because Zeeschuimer is set up in such a way that it cannot know what to pseudonymise before uploading. I suppose it could be also be a 4CAT user setting (pseudonymise uploads yes/no), except we don't have a user control panel (yet), only an admin control panel.

This is working now, but I want to wait until a new 4CAT release to include it in Zeeschuimer, because some small changes were needed on 4CAT's side as well.

Amazing! And no rush
