dateKeys-dart

Stage 5b: the vectors of Go for the security area

tool/security_go_vectors.go writes test/vectors/security_vectors.json
with package capsule of datekeys-go at c531e93, the draft v0.12, run in
its module without changing it, and a part of it for Node.js in
security_vectors.g.dart:

- the commitments: PayloadCommit, ControlCommit of the control of every
  fixture and of controls built with extensions, in each format, with
  the text of the error where CONTROL_SIG cannot be encoded, HeadDigest,
  SignersDigest, AuthorMessage, AuthorCode, also of messages that
  AuthorMessage never writes, SigPart and SealSubject;
- the encoders of SECURITY_CBOR, author-signature and seal;
- 1730 evaluations of SECURITY_CBOR with EvaluateSecurityIn in 23
  contexts, and EvaluateSecurity without one: the outer map,
  author-signature and seal broken in every way of their schemas and
  limits; signatures of alg 1 valid and invalid, saved or not, with the
  cases of Taming the many EdDSAs made over AUTHOR_MESSAGE by searching
  the context; and mutations of nine bases from a fixed seed. Each case
  gives the verdicts, the key and the label of alg 1, the lines, alg and
  seal_type as read, and the parts that only the reader of CMS evaluates;
- Lines and SealedAt of verdicts built with every pair of verdicts and
  the details of signers and seals;
- holderText, reached with go:linkname, on names at the limit of 64 code
  points and drawn from the seed.

The files are ASCII, and every run writes the same bytes.
