(Ozone) Strip metadata from PNG files #351

Closed jdgleaver closed 4 years ago

jdgleaver commented 4 years ago

This PR simply strips the metadata (optipng -o7 -strip all) from the Ozone PNG files not generated via the src/xmb/monochrome/export_ozone.sh script

(I forgot to do this when setting the transparent pixel colours in PR #347!)
