Additional Formats Support

[chrisburnor]

A few additional file formats for the prototypes would be helpful. In particular Ron and Toml support would be a nice extension to Yaml and Json and are supported by existing libraries.

You are able to use this by implementing your own ProtoDeserializer (replace the YAML deserializer with your own), such as:

bevy_proto/src/plugin.rs

Lines 88 to 99 in fb7bde3

	#[derive(Clone)]
	struct DefaultProtoDeserializer;
	impl ProtoDeserializer for DefaultProtoDeserializer {
	fn deserialize(&self, data: &str) -> Option<Box<dyn Prototypical>> {
	if let Ok(value) = serde_yaml::from_str::<Prototype>(data) {
	Some(Box::new(value))
	} else {
	None
	}
	}
	}

Then just add it as an option in ProtoPlugin.

But maybe I'll change the default serialization to be feature-dependent. Then you can choose from a few common ones such as YAML/JSON, RON, and maybe one or two more built-in to the crate 🤔
