Using DuckX to parse .docx files similar to the way we parse PDF.

Leaving as draft until we can resolve the fact that we are chunking paragraphs and not pages. The best way to fix that is to stream the document instead of grabbing large discrete chunks of it, but this is blocked on merge of #2969 because that also touches chunkStream.

edit: With the recent changes, this PR now streams the docx statefully so we don't need to worry about seeking to a particular run/paragraph every time we enter the database code, and we slice by time and not some arbitrary unit such as pages to allow the reader code to be more generic.

If we don't copy DocumentInfo, we can store uncopyable objects inside of
it.

We already use 'doc' to refer to a parsed representation of the
document, not the file info.

Apple Clang still does not support __cpp_aggregate_paren_init (P0960R3).

okay, so chunkstreamer is a class now? what is the lifetime of this object?

It's matched to the lifetime of Database. I thought it would make sense to separate the state from the main Database class, since they have separate responsibilities, even though they work together.

This should be a separate PR altogether.. sorry, was talking about first commit in this PR... the way we prefer to do PRs is just very different. Not sure why bumping the version is the first commit in this PR

That change isn't part of this PR anymore after the merge, since it was also done on main. I wanted to make sure the version number was no longer v3.3.1 and I didn't want to have to wait until a PR was approved and merged in this repo in order to start working on this change. Would you like me to rebase the PR so that commit goes away?

No, that's okay. Thanks for the explanation.

The build passed for Mac and Linux, and on Windows after adjusting the CI timeouts (since build-and-test-gpt4all-chat is missing the timeout adjustment, even though the installer jobs have it).
