Allow to export animation to PNG sequence using commandline
Summary:
Implementation of feature request made in https://bugs.kde.org/show_bug.cgi?id=364046
This patch adds new commandline option "--export-sequence". Just like "--export" option, it should be used together with "--export-filename" option.
Example:
krita --export-sequence --export-filename ../../persistent/output/file.png /home/appimage/persistent/test.kra
If KRA file has no animation, then this command prints "This file has no animation." error and does nothing.
