devel/difftastic: update to 0.32.0

0.32 (released 7th August 2022)
-Improved performance in many cases, particularly for files with a fairly flat
 structure.

-Difftastic now treats the path /dev/null as an empty file, even if that path
 doesn't exist on the current machine. This fixes a crash when using difftastic
 with git on Windows.
