 Warning: **obviously multihash values bias the first two bytes**. Do not expect them to be uniformly distributed. The entropy size is `len(multihash) - 2`. Skip the first two bytes when using them with bloom filters, etc. Why not _ap_pend instead of _pre_pend? Because when reading a stream of hashes, you can know the length of the whole value, and allocate the right amount of memory, skip it, or discard it.
