Codecs and Funny Looking Functors
summary
Uses scodec to build actual encoders/decoders: shows the greedy-string problem, implements a size‑prefixed (var) encoder over bitvectors and Attempt results, composes primitive codecs into a DNS packet codec, derives ISOs to move between bitvector/bytearray/tuples, and plugs codecs into Netty/NIO as a profunctor IO abstraction. Produces a working DNS client that round-trips UDP packets and returns multiple IPs, with STUN mentioned as another real protocol example.
