v0.21.4

• Exports loadAsyncData() function — it loads asynchronous (or synchronous) data into the global state, the same way as useAsyncData(), and useAsyncCollection() hooks do. It is intended for niche situations when a direct, imperative global state manipulation with such function makes more sense than using the hook.
• [#126] Corrects AsyncCollectionT type definition.
• Misc documentation corrections.
• Update of dependencies.
