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.

<h2>A note on licensing</h2>
<p>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.</p>

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

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