   Non-DER versions, which just fill in 64 bits in some canonical order.

   Alternately: make the opaque structure a canonical order.

   See my laxder branch, it also adds those. I’ll PR when I either decide to split it off from the DER rework, or tests for that are finished.

   Yep, looks good! Please document the serialize format (at a glance, it’s 32 byte unsigned BE r value followed by 32 byte unsigned BE s value).

   I’d still like a “is_normalized” or “is_canonical” for the s-value test BTW, but I can implement my own with these.
