Title: Add a get_raw method, which allows users to access the raw value of a header

This method is marked unsafe, as it should not be used in normal code
because it can easily invalidate header representations.

Fixes #10

We might want to *not* mark this method unsafe, but that's mostly a matter
of convention. What are your thoughts on this?
