-v raises the CLI's log level per repeat; -q prints only fatal errors (closes #212)

Every line quak prints on stderr now goes through one log, in
src/cli-log.ts, at one of six levels. The default, info, prints what quak
printed before. -v adds each retry and the start and end of each refresh
and ML data fetch; -vv adds each request with its result. -q prints only
the line a failing command exits with, and is refused with -v. Both are
program options. withRetry reports retries through a new onRetry, and
ApiClient reports requests through a new onRequest; the CLI logs what
they report. --json now changes stdout only, so backup and --json runs
log their progress on stderr.
