Slim Down the Dependencies

[zachcp]

As of v0.1.0 the builds take over 10 minutes. This is due to the rather large dependency tree. There are a few ways to slim down the tree.

1. Remove Bevy.
   • This is at the top level to make dependency handling understandable but leads to large builds. I wanted to keep all of the creates connected until we get a bit further on the selection API. If this continues to be burdensome, we can move this dep out of the workspace. That will help but won't fully solve the problem.
2. Remove ORT/ndarray
   • I am using ORT as a wrapper for the ONNX runtime but it turns out that Candle also has an ONNX-wrapper in candle_onnx.
   • main blocker is my initial test led to an inexplicable dimension error
3. Remove ndarray-safetensor
   • I am using ndarray-safetensor to serialize between the Candle and ORT/ndarray ecosystems. Fixing 2 will eliminate 3 but if I can serialize directly to NDARRY without going through this library that will dave a dep. Code in ferritin-onnx-models/src/utilities.rs
