Issue

Address #1787.

How did I fix it

Rename bitfield_bytesto pack_bits and make this function return BYTES_PER_CHUNK-byte chunks.

p.s. it seems the spec was misleading but the implementations are all good? /cc @protolambda to confirm.

* `mix_in_length(merkleize(pack(value), limit=chunk_count(type)), len(value))` if `value` is a list of basic objects.
* `mix_in_length(merkleize(bitfield_bytes(value), limit=chunk_count(type)), len(value))` if `value` is a bitlist.
* `mix_in_length(merkleize(pack_bits(value), limit=chunk_count(type)), len(value))` if `value` is a bitlist.

mix_in_length(merkleize(pack(bitfield_bytes(value), limit=chunk_count(type)), len(value)) would also work. But being explicit here is not a bad idea.

Also confirm that the spec was misleading here, good catch and fix. Thanks.
