Meros: Multipart Response Utility

Meros is a lightweight (642B gzipped) utility designed to simplify the parsing of `multipart/mixed` HTTP responses, a common pattern in technologies like GraphQL for deferred or streamed results. Currently at version 1.3.2, the project appears actively maintained with a stable release cadence. Its key differentiators include a zero-dependency runtime, a minimal footprint, high performance, and seamless integration with `fetch` and `rxjs`. It supports both Node.js (requiring `node >=13`) and browser environments, automatically parsing JSON content within parts. Meros returns an `AsyncGenerator` for `multipart/mixed` responses, or the original `Response` object for other content types, offering flexibility for use in middleware or chained `fetch` calls.
