Resolves: #20

Open issues:

• Multiline quotes + newlines: search for "There’s a few tactics that can mitigate these latency issues, but no real definitive solution. You can:"
• Choose closest note (in filesystem) when searching for linked note. I. e. prefer ./note over ../note
• Mismatched tags at multiple test cases. Maybe they can be ignored instead of failing.
• Testcases test-sublists-invalid and, test-sublists-valid -> remove whitespace in list
• Encryption
• Testcases:
  • sanitize_fulltest
  • tana-highlight-test-2
  • test-monospace-codeblocks
  • test-webclip_article
