Authorship

This code is heavily (like, REALLY heavily. Like, they did all the hard parts and I just messed around with adding typing) taken from https://github.com/DLehenbauer/jszm , which itself is taken from the jszm v2.0.2 by zzo38. While no official license statement is in the original source, it does state the it is in the "public domain", which for these purposes I am treating as at least as open as the MIT licence. If it turns out I am wrong about this, and you are one of the upstream authors, please contact me and we'll get it resolved immediately.

While jszm relies heavily on generators, for the most part I have switched things over to classes and promises. To a certain extent, this is just a matter of taste - generators essentially allow you to memoize the state of a stream within the function. Since I'm wrapping the whole thing up in a class that itself can have state (and share it between the various implementation functions) the generator paradigm does less for me... And I really wanted to make the various functions async so that I could do some more interesting things with them. If you are someone who really likes generators it's not THAT hard to switch them back - I may end up writing an adapter class one of these days.
