The difficulty is in deciding what the api should be. Does it give you a
real bitstream or only a byte aligned one? If I ask for 3 bits then 15
bytes what does it do? Does it assume I meant 3 bits, then pad to the
next byte boundary and get 15 bytes, or does it mean get 15 bytes but at
this 3 bit shift offset?
