Replace old Animation Code with Sausage64

[Byterset]

The old animation code should be replaced with the newly adopted Sausage64 library. Old Model exports should be re-exported via the appropriate tools and the old exports & tools removed

[Byterset]

resolving this issue includes:

• removing the old animation code
• remove legacy tools for animation export and eventually include sausage64 tools
• handle animated objects in level file structure separately

Just a heads up that Sausage64 had a big update recently which adds in binary model asset support (As well as a lot of new features). Might be worth pulling in the new changes 🙂

@buu342 thanks for the heads up :) I created Issue #12 for that and will have a look at the updates!
