This is an implementation of asynchronous streams framed as Netstrings.
A netstring is a binary protocol for length-prefixed frames,
using decimal strings as variable width integers.
For example, the frame 5:hello, corresponds to the message hello,
where 5 is the length of hello in bytes.
This implementation relies particularly on the pure JavaScript notion of a
stream, using async iterators of Uint8Arrays.
By convention, these may be ranges of a ring buffer, so a stream owns a byte
range it receives from next until the next time it calls next.
