Bevy common assets

This Bevy plugin includes generic asset loaders for common file formats.

Supported formats:

`format`	`feature`	`example`
`json`	`json`	`json.rs`
`ron`	`ron`	`ron.rs`
`toml`	`toml`	`toml.rs`
`yaml`	`yaml`	`yaml.rs`

Usage

Enable the feature(s) for the format(s) that you want to use.

Define the types that you would like to load from files and derive serde::Deserialize and bevy::reflect::TypeUuid for them. The latter requires a unique uuid as an attribute:

#[derive(serde::Deserialize, bevy::reflect::TypeUuid)]
#[uuid = "413be529-bfeb-41b3-9db0-4b8b380a2c46"] // <-- keep me unique
struct Level {
    positions: Vec<[f32;3]>,
}

With your types ready, you can add asset plugins for each type. Every plugin gets the asset type as a generic parameter. You also need to configure custom file endings for each type:

use bevy_common_assets::json::JsonAssetPlugin;
use bevy_common_assets::ron::RonAssetPlugin;
use bevy_common_assets::toml::TomlAssetPlugin;
use bevy_common_assets::yaml::YamlAssetPlugin;

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_plugin(JsonAssetPlugin::<Level>::new(&["json.level", "custom.level"]))
        .add_plugin(RonAssetPlugin::<Level>::new(&["ron.level"]))
        .add_plugin(TomlAssetPlugin::<Level>::new(&["toml.level"]))
        .add_plugin(YamlAssetPlugin::<Level>::new(&["yaml.level"]))
        // ...
        .run()
}

See the examples for working Bevy apps using the different formats.
