Specification 0.16 draft: a seal without accuracy, drand's JSON read strictly

The draft v0.16 of datekeys-go at 4f78854 (branch v0.16): SPEC_VERSION
0.16, and testdata, wordlists and annex synced from that commit. The
annex is §79 of the draft, with the CC BY-ND 4.0 license of the
specification in its title and the key of words in 79.7.

A seal without accuracy proves nothing before the opening date (§29.7,
§29.11, as 7e3b810): a valid seal is S4 only when its token carries
accuracy and t plus the accuracy is before round_time; otherwise S5,
with the first reason that holds: late, no accuracy under the BTSP
policy of ETSI EN 319 421 (0.4.0.2023.1.1), or no accuracy. cms.ts reads
hasAccuracy and the policy of the token (tokenIsBTSP); securitycms.ts
gives SealReason, Detail.sealReason and SignerLine.reason; S5 has no
fixed text any more, and verdictLines writes it and the line of a signer
of F6 with the reason, the texts of Go byte for byte (sealReasonText).
encryptFiles returns the verdicts of the area it wrote in
Encrypted.security, as Result.Security of Go, so that a writer warns of
a seal without accuracy (§62.1 rule 19).

drand's JSON is read strictly (§47.1, as b570338): parseDrandJSON, as
ParseDrandJSON of Go, reads RFC 8259 JSON in valid UTF-8 whose value is
an object, with no name repeated in any object, names compared exactly
once their escapes are decoded, a lone escaped surrogate malformed, the
round a number without sign, fraction or exponent from 1 to 2^53 - 1,
and signature and randomness strings, with the error texts of Go.
ParsedRelease is now a Release: no round above 2^53 - 1 is read. The
page reads the answers of the relays with it (drand.ts), as the client
of Go does, and the pasted release with strictJSON and jsonRound
(release-input.ts), so that it never reads another round than step 10.

Tests: security_cms.json with seal_reason (143 cases), the 38 JSON
inputs of release.json, the new cases of signature2_test.go and
drandjson_test.go (with the escapes written as escapes), and the new
fixtures: format3_time_and_key_words opens with the identity that the
words of its words_text give with normalizeWords and wordKey, in the
library and in the page, and format3_full_chunk, whose PAYLOAD_AGE ends
in a full STREAM chunk, opens. check-build.mjs counts words_text among
the secrets of the fixtures.

Reference files made again with Go at 4f78854: mutation-texts.json (its
spec field only), ibe-vectors.json (the two new fixtures, the rest
unchanged) and signing-vectors.json, in an export of 4f78854 with the
same frozen samples read again: the capsules are the same, and the
tokens of the sealer, without accuracy, now give S5.
