f3probe should provide progress feedback while running

[sndcrde]

f3probe should provide progress feedback while running, otherwise it may be difficult to say if f3probe is doing something useful for a half an hour or just hanging.

I'd suggest every minute f3probe should give the user some feedback about its progress: what it's doing, % completed and how much time (estimated) is left until completion. For those who don't want any kind of feedback there perhaps should be --quiet option that disables all feedback, or maybe not
