Well, that assumption has the advantage that the same init function can be used
etc. With different structs it would get real ugly to use them both.

Yes, I'll probably implement that in the end (it does still mean it is not
possible to inline the _whole_ codec though, so one additional function call
per 33 bytes).
However one approach to allow including get_bits multiple time would
be to wrap _everything_ in rename macros (I assume this will be possible
somehow for the macro definitions as well, not so sure there though).
However I suspect this would make the code real ugly and is not really
