A command like this doesn't work:
zotero-cli --group-id 2259720 item --key 55ZH3TY2 --addtags "Test1" "Test2" --addtocollection FQMTV37B
This is because the addtags and addtocollection commands are executed sequentially. It would be ideal if all addtags/removetags/addtocollection/remotefromcollection were combined into the same request.
