Refactor Codebase to Functional Structure

[ohare93]

Should work pretty much the same, but uses much more object orientation and a somewhat planned structure! :sweat_smile: rather than the hodgepodge that I originally created :scream:

Hopefully this will make it easier for others to add their own changes!

Some changes include:

• Json representatons refactored to Yaml
• CrowdAnki files have their own Yaml representations and classes
• No longer needs to write DeckParts to a file (but still can, as Yaml)
• A file and path will be automatically created where they do not yet exist on write
• Yaml verification using Yamale

It has been a mammoth task, and I am just happen that everything runs again. Now that this massive restructuring (rewriting?) is complete I think I can make headway on the wildly important tasks that have been lining up! :grin:

---

Some tidy up tasks from this restructure I have yet to finish but are not necessary to release, which I will make an issue for, include:

• Remove dependency between File Manager and Media files.
  • Set which media folders to read in the builder file instead.
• Remove the global config
• Fix the hundreds of unit tests that broke due to this change
• Deck Part Notes have a new Yaml structure, but never group themselves by Note Model / Tags, as they were intended to do. Implement this as an option in the deck_part_from parts.
• Flags are supported in Deck Part notes, but cannot be written to Csvs. Make this possible, but Tags and Flags not necessary.

@rcshadman fyi, as I see you have forked, big changes have occurred! :grin: these changes will make it much easier to understand and develop on top of, if that was your intention :+1:
