Removed channel-based server loop goroutine, solving eaten initial byte issue.
...
Made receivers on hkex.Conn mutators *Conn again (whoops)
TODO: Consider: padding (? probably not, XORKeyStream OFB/CBC/etc. modes prevent
constant header/crib exposure, and would add lots of complexity to Read/Write)
TODO: Add CTR, other modes
