Updates all deps needed to support passing lists of byte arrays where they have been created from multiple input buffers. When reading multiplexed data, all messages arrive in length-prefixed buffers, which means the first few bytes tell the consumer how many bytes long next chunk will be. One length prefixed chunk can be delivered in several payloads from the underlying network transport. The first payload can also include the length prefix and some or all of the data, so we stitch these together in a `Uint8ArrayList` to avoid having to concatenate `Uint8Array`s together. Previously once we'd received enough bytes to satisfy the length prefix we'd concatenate the bytes together, but this is a potentially expensive operation where transports have small message sizes so instead just pass the `Uint8ArrayList` to the consumer and let them decide wether to concatenate or not as some consumers will be smart enough to operate on lists of `Uint8Array`s instead of always requiring a contiguous block of memory. BREAKING CHANGE: Streams are now `Duplex<Uint8ArrayList, Uint8ArrayList | Uint8Array>`
