It used to be non-const, but hwright constified it a while back. The
idea was that our APIs would write into it, but third-party users
should not. Thus, const.

The "public" way to create one is via finalizing a context, parsing
hex data, computing a checksum for a byte block, etc. Just no real way
to shove bytes into that structure explicitly.

There is an argument that third parties will need __from_digest just
like we do, as they upgrade from the old digest-style APIs. I'd
consider waiting to hear from them before officially
supporting/exposing that API.
