Say 0.16.21 where the docs still said 0.16.20

The README badge still read 0.16.20, in both the label and the shield it
links to. It is the first version number a reader sees and it was the one
place the prose update missed, because it is HTML rather than Markdown.

Two entries had gone further than stale and were wrong. FEATURES said
occurrence ids are not stable across a write, and KNOWN-ISSUES carried
that as a live hazard with the five-week series that proved it. 0.16.21
fixed exactly that: an occurrence is identified by its recurrence id now,
and holding an id across a write keeps it on its own date. Both entries
say so, keep the old behaviour and the evidence for it because the client
still supports 0.16 as a whole, and record what replaced it.

The defence in the client stays either way, and the reason is written
down: re-resolving by recurrenceId costs one lookup, a date can still
leave a series, and 0.16.20 is still a server someone may be running.

The KNOWN-ISSUES header now says the live instance runs 0.16.21 and,
unlike the upgrades before it, that this one was re-run rather than read
against the diff — with what was exercised by hand.
