The general pattern of stream muxers is to yield protocol stream data framed by some additional metadata - stream id, flags, etc. The frame data can be prepended/appended to the protocol stream data by using a `Uint8ArrayList` instead of a `Uint8Array`, this removes the need to copy the protocol data into a new `Uint8Array` for every frame. The new `@libp2p/interface` version allows muxers to emit `Uint8ArrayList`s as well as `Uint8Array`s so we can send protocol stream data to a transport in a no-copy operation.
