Some work around getting data out of Confluence.

Some actions use the Confluence API and some of those require you to authenticate using a token.

• get_spaces.py retrieves a list of all the Spaces your user can see in a Confluence wiki, and dumps it out to a spaces.json file.
• confluence_object_defs.py contains dataclass definitions for types of object observed within Confluence XML exports.
• wiki2storage.py uses the Confluence API to convert between Confluence's internal formats, as well as the presentable HTML-segment "view" format.
• space_export.py is some very rough code for parsing the entities.xml file you get from a Confluence XML export into a collection of objects, and dumping out the pages as separate files. Several problems with using this remain unsolved.

• what to name dumped files
• hierarchy of files
• wiring the links back together
• many things around attachments
• rendering comments to pages
• some problems observed around <![CDATA[ use in body content, not fully diagnosed yet
