 MegaMap is a TypeScript library designed for advanced key-value mapping. It extends the native JavaScript `Record` object
 and integrates additional features such as caching, loadability, and automatic expiry of entries. MegaMap is built upon
 two foundational classes, `LoadableMap` and `CachedLoadableMap`, each offering distinct capabilities. This library is
 ideal for sophisticated mapping solutions where enhanced control over data storage and retrieval is needed.
 
 Ideally, this library is meant to be used in conjunction with a data store (e.g. a database, API, etc.),
 and/or state management solution, such as [pinia](https://github.com/vuejs/pinia).
