NIFI-3737 - Ran optipng on all png files

> Optimize png resources with optipng

> Key: NIFI-3737
> URL: https://issues.apache.org/jira/browse/NIFI-3737
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Bryan Rosander
> Assignee: Bryan Rosander
> Priority: Trivial
>
> [Optipng|http://optipng.sourceforge.net/] is a utility that tweaks
> compression parameters in png files to reduce their size without losing
> quality. Running this on all the png resources in NiFi reduces their total
> size by about 35% (12M -> 7.4M).
> This isn't a huge change but it should be very low impact and will hopefully
> make the ui feel a bit snappier with smaller resources.
> [Command to optimize all
