~refactor: remove dependency on genanki

[MartinBernstorff]

• What is the new flow? Probably want to detail this as much as possible.

MemiumPrompt -> AnkiPrompt -> AnkiConnectPrompt

• Are the methods available on AnkiConnect?

  • addNote
    • (?) What happens if you call addNote with a deck that doesn't exist?
    • deck was not found error. Means I have to handle that as well.
  • updateNote
  • deleteNotes

• Seems there is more manual handling

  • What if the deck doesn't exist?
    • Have to manually add it.
  • Do I have to infer which notes to update and which to add?
    • Yes, raises an error if a note id already exists. Have to update instead.
