`into bits` is a bad name because it is not a traditional type cast to a
`bits` type like all the other `into` commands.
Instead it is a pretty printer generating `string` type output. Thus the
correct bucket is `format` and its subcommands.
# Description
Fix `into bits` to have consistent behavior when passed a byte stream.
# User-Facing Changes
Previously, it was returning a binary on stream, even though its
input/output types don't describe this possibility. We don't need this
since we have `into binary` anyway.
# Tests + Formatting
Tests added
