Add support for Ulysses 16 XML-based sheets

[andymatuschak]

In Ulysses 16, the file format for sheets has changed from plaintext files to a new XML format. All new sheets created in the last few months have consequently showed up as "Unknown type" in the workflow. This commit adds support for the new format.

Thanks for info and the pull request. Will take a look when I get a chance and create a new release.

Thank you very much, @andymatuschak. This commit has given a second life to this excellent extension of @robwalton. 🙏🏾

I've never built an Uylsses workflow before, so bare with me. Can you kindly (or someone else) tell me how I would compile an .alfredworkflow bundle from your fork, @andymatuschak? I do have python and deanishe/alfred-workflow installed.

Update: Found out that a alfredworkflow file is just a renamed zip and now this workflow works again, hooray. Thanks for the fork!

Does this still work for you? Would love to use this with the current version of Ulysses
