Closes #26.

TODO List:

• [x] Rotate item renders correctly.
• [ ] Update rendered item on shulker opened.
• [ ] Options for scaling...?
• [ ] Options for rendering.
• [ ] Reorganize code to simplify development (e.g. move chesttracker mixins over).

Thanks for looking into this Adam.

Flagging some other issues that I'd want resolved before properly adding this as a feature (requires server-side support):

• Doesn't update in real time (e.g. when another player interacts with the shulker)
• Doesn't load information about pre-placed shulkers (I note that in your TODO list you plan to update upon opening, but ideally that wouldn't be necessary)
• Given many servers and shulkers, I can see these config files blowing up. Ideally the loaded icons would be in memory only (retained based on proximity), and updated upon shulker interaction (by any player) or loading. This maintains real-time updates without unnecessarily adding a config file.

I have some ideas about how I'd go about implementing this (using a subscription system across server/client), but it will take some time due to my availability.

Great! In that case, I will stop working on trying to update icon onUse. I have a couple more unpushed changes (related to rotation) that I will clean up and push, but then I will be unable to be helpful much more because I haven't done any work with networking.

Thanks Adam. I'm going to close this one for now (see #26), but it will definitely be a handy pull request to reference should I look into this further in future.
