ec95dda18f Unify crawling and downloading steps 
Now, the progress bar, limiter etc. for downloading and crawling are all handled
via the reusable CrawlToken and DownloadToken context managers.

afac22c562 Handle abort in exclusive output state correctly 
If the event loop is stopped while something holds the exclusive output, the
"log" singleton is now reset so the main thread can print a few more messages
before exiting.

552cd82802 Run async input and password getters in daemon thread 
Previously, it ran in the event loop's default executor, which would block until
all its workers were done working.

If Ctrl+C was pressed while input or a password were being read, the
asyncio.run() call in the main thread would be interrupted however, not the
input thread. This meant that multiple key presses (either enter or a second
Ctrl+C) were necessary to stop a running PFERD in some circumstances.

This change instead runs the input functions in daemon threads so they exit as
soon as the main thread exits.

4b104b6252 Try out some HTTP authentication handling 
This is by no means final yet and will change a bit once the dl and cl
are changed, but it might serve as a first try. It is also wholly
untested.

e4f9560655 Only retry on aiohttp errors in ILIAS crawler 
This patch removes quite a few retries and now only retries the ilias
element method. Every other HTTP-interacting method (except for the root
requests) is called from there and should be covered.

In the future we also want to retry the root a few times, but that
will be done after the download sink API is adjusted.

4b68fa771f Move logging logic to singleton 
- Renamed module and class because "conductor" didn't make a lot of sense
- Used singleton approach (there's only one stdout after all)
- Redesigned progress bars (now with download speed!)
