Lighter import process

[phildenhoff]

• Automatically sync new annotations from Raindrop on a configurable schedule
• Put imported annotations into one page, instead of many. See omnivore-app/logseq-omnivore for inspiration
• Choosing between this behaviour and the existing one should be optional

That will likely mean that the diffing process goes away with the one-page import. That's a significant change in how to import.

I'm open to other suggestions on possible improvements to this process! If you like the existing page-based import, but would like to see some improvements, let me know!
