Title: Remove binary.{Read,Write} in favour of doing it by hand

The encoding/binary.{Read,Write} methods use reflection which is slow. This is
ok for prototyping but has a serious performance impact. In each case, we
know exactly what we're trying to write out, so we'll allocate our own buffer
and do the explicit conversion ourselves.

As an example of the performance improvement this makes, here are the results
from an (internal) benchmark:
