Thinking a bit more about it, this may open a can of worms. If you
allow conversion between a bitvector and a u8vector, then what about
u8vector and u32vector (four u8 packed in one u32)? SRFI 160 does not
support conversion between homogeneous vectors of different types
either, so maybe we just leave it out and figure that out in a new
srfi (if it ever comes). I won't stop you from adding new conversions
in this srfi, of course :)
