scripts: Added support for SI-prefixes as iI punescape modifiers

Browse Source 
This adds %i and %I as punescape modifiers for limited printing of
integers with SI prefixes:

- %(field)i - base-10 SI prefixes
  - 100   => 100
  - 10000 => 10K
  - 0.01  => 10m

- %(field)I - base-2SI prefixes
  - 128   => 128
  - 10240 => 10Ki
  - 0.125 => 128mi

These can also easily include units as a part of the punescape string:

- %(field)iops/s => 10Kops/s
- %(field)IB => 10KiB

This is particularly useful in plotmpl.py for adding explicit
x/yticklabels without sacrificing the automatic SI-prefixes.
