The connection should emit a WindowUpdated event on INITIAL_WINDOW_SIZE change

I think the connection should emit a WindowUpdated event on receipt of a settings frame that changes the INITIAL_WINDOW_SIZE. This is because [this frame is valid after the receipt of...

2

Good artists copy, great artists steal. One of @njsmith's great decisions with [h11](https://github.com/njsmith/h11) was to write his [buffer](https://github.com/njsmith/h11/blob/master/h11/_receivebuffer.py) in terms of bytearray. This has some major efficiency gains on Python...
