dldr: Batching and Caching Utility

dldr (pronounced "dataloader") is a minimalist JavaScript utility, currently at version 0.0.10, designed for efficiently batching and caching operations. It is particularly useful in data fetching scenarios, such as optimizing queries within GraphQL resolvers. The library distinguishes itself by its extremely small footprint (367B gzipped) and its use of `queueMicrotask` to schedule and execute batched load functions within the current event loop tick. This mechanism ensures that multiple requests for the same or different keys, made in quick succession within the same microtask queue, are consolidated into a single call to the underlying data fetching function. dldr offers both a basic batching mechanism and an extended version accessible via `dldr/cache` that incorporates an in-memory `Map`-based cache, preventing redundant data fetches for previously loaded keys. Its primary goal is to improve performance by reducing the number of requests to databases or APIs, positioning it as a lightweight alternative to more feature-rich dataloading solutions. While in early development, its API is straightforward, centered around `load` functions that accept an array of keys and return corresponding results.
