Someone should not reasonably expect a coun flag to go up to billions, millions, or even thousands. 255 should be sufficient for anyone, right? The original type was selected to be consistent with `ArgMatches::occurrences_of` but that is also used for tracking how many values appear which can be large with `xargs`. I'm still conflicted on what the "right type" is an wish we could support any numeric type. When I did a search on github though, every case was for debug/quiet flags and only supported 2-3 occurrences, making a `u8` overkill. This came out of a discussion on #3792
