Provides a teeny way to have some nice byte structures that's easy to use.
It's all provided in one structure and many function implementation.

A note on licensing
-----------------------
This library changed from the LGPLv3 to MPLv2 as a result of LGPL's requirements for freedom of source on static linking which rustc does.

I've chosen to use the MPL as it is a weaker but still copyleft license that allows you to statically link.

The MPL applies retroactively to all previous versions of this library and will be used for all future versions.
