lib/src/header.dart, control.dart and accesskey.dart port DecodeHeader,
EncodeHeader, DecodeControl and EncodeControl of package capsule and
package accesskey of datekeys-go at c531e93, in the layers of spec §69.1
and with the texts of Go: the limit of the frame, the type tag and the
schema version, the CBOR profile with the re-encoding and the CDDL, keys 6
and 7 of CONTROL_CBOR versions 2 and 3, and only then the DateKey of the
header and access_type and access_material of the .dkk. The .dkk is
written with the rule of spec §72 for the extensions of the specification
and read back before it is returned, as MarshalBody. I_PAYLOAD and
access_material are copied once and wiped on every path; their objects
print without them. The access policy is the enum AccessPolicy.
The tests read every fixture of testdata/: the PRELUDE, the sections and
header_binding of the 24 capsules, their header and control decoded and
written back, the round time of their DateKey, P, and in format 3 the frame
of BODY, the area, the head and the files; the six .dkk with their
capsule_digest. And the shared vectors dk1.json, quicknet_rounds.json,
profile_quicknet.json, padding.json and the 172 schemas of cbor.json,
which stage 1 left aside, each decoded by its schema and written back.
