-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 fatal lines, and is refused with -v; both are program options. Every non-zero exit logs one fatal line, so a run that exits 1 because files failed says how many and where to look. Every line reporting a failure is at error. --json changes stdout only, so backup and --json runs log their progress on stderr. withRetry and ApiClient report retries and requests through new callbacks.
