vf_showinfo: minimum widths for some early fields
Depending on FPS, the pts_time string often changes length:
... pts_time:36.1 ...
... pts_time:36.1333 ...
The length changes make the output bounce around horribly, making it
hard to scan down a column farther right than pts_time.
The solution is to set minimum widths for n, pts, pts_time, and pos.
This patch doesn't touch any of the fields in mean / stddev.
The widths aren't intended to be wide enough that they're never
exceeded, but you'll see only an occasional ripple to a new alignment,
rather than bouncing. (Some fields, like pos, increase monotonically,
which is why I left the minimum width for the field be smaller than it
often gets to.)
