Feat: Add Ollama Support

[CPritch]

Hey there, here's a PR for adding Ollama to AnkiBrain. Had some fun during my time off to get this implemented. I think I've covered most of the bases here and didn't want to tinker too much with your current codebase or make any sweeping changes.

I suspect you'll want to change this PR to be merged into a new 0.7.4 branch. I'm not 100% clued in on your release process so I haven't touched anything like version numbers or change logs. Just MVP as far as I can tell.

I've added the following changes:

• Reworked Advanced Settings to use Grid layout
• Add 'Set Ollama Host' menu item
  • For pointing at any custom Ollama hosted instance
  • Adds new setting 'ollamaHost' to settings.json
• Added LLM Providers to Advanced Settings Page
  • OpenAI or Ollama
  • Adds new setting 'llmProvider' to settings.json
  • Available Ollama models are loaded over API
• Updated Local ChatAI initialization
  • Now checks for provider and ollama server availability
  • Loads available ollama models over API
• Added JSONRepair to fix nearly correct JSON returned by LLMs

I believe it should handle the settings changes pretty gracefully but I'm not 100% on whether I've missed anything. I believe I've updated the python requirements correctly etc. I haven't been able to test all behaviour though as I don't use OpenAI.

Let me know if you have any issues or want me to change/address anything about this PR. Cool project though! Can see you've put a bunch of time into the codebase, I have a ton of suggestions for refactoring in general that I might be able to help with at some point soon. Just would help trim down the fat before adding any more functionality.

Thanks for the massive pull request! It'll take me some time to get to reviewing this, but I plan to. I would like to upgrade dependencies where I can then integrate these changes. Ollama support will be great to have!

Hi @CPritch I downloaded your PR (from https://github.com/CPritch/AnkiBrain/tree/feat-ollama), and unzipped it inside the addons21 folder, however, after installing it, I get a "Your file couldn't be accessed" error in the GUI. Did that happen to you as well while developing / testing?

Yeah, i am also getting the same error. @CPritch can you please help me resolve that error?
