wordlist.ts does what wordkey.Generate, CheckList and Bits of Go do at
27a75ee, with their texts: generateWords draws different words, 7 by
default, with crypto.getRandomValues; wordBits is their strength;
checkWordList refuses a list of fewer than 2048 words, with two words that
are one once normalized or with a character outside the alphabet of its
language, which the code gives and not the list. readWordList takes a list
only with the SHA-256 pinned for its language, in UTF-8 and accepted by
checkWordList: no list is trusted, not even those of DateKeys.
wordkey.ts gains wordRules, which loads the Unicode tables once for a
caller that reads many words; normalizeWords and checkWords use it.
