Ed Page 31b22d1a51 perf(parser): Take up less memory with ArgAction::Count 
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
