I'm OK with that. We also have the option to, instead, remove debug info

This is what I got with the attached diff changing the build type.

Before:

256M    /usr/ports/packages/amd64/ftp/prusaslicer-2.9.4.tgz
875M    /usr/local/bin/prusa-slicer

After:

76.9M   /usr/ports/packages/amd64/ftp/prusaslicer-2.9.4p0.tgz
43.0M   /usr/local/bin/prusa-slicer
