I should probably make it more clear that data-binary-ieee754 is for
special use cases; for most people, using something like this will be
much faster since it doesn't have to poke around the individual bits:

putFloat32be :: Float -> Put
putFloat32be = putWord32be . unsafeCoerce

I needed "real" IEEE754 binary support for round-trip parsing, where
(for example) maintaining the particular bit pattern of a NaN is
important. For 99% of people, the "unsafe" method will work fine.
