Purely functional gRPC and HTTP/2 with OCaml

Let me present you a from-scratch, purely functional implementations of HTTP/2 and gRPC in OCaml - desined around Eio's effect-based concurrency and immutable internal state in mind for clean code and easy iterations. Motived by real-world memory leaks in high loads at Dialo, I rewrote the entire HTTP/2 implementation to satisfy the needs for streaming-based performance in gRPC. Let me show you how to design a network protocol's API the right way - the functional way!
