Patches: Leave objects.package images uncompressed

Strange discovery while fixing #25:

The school icon (group ID 0x856ddbac, instance ID 0x7f2dcbc6)
is invisible both in the career tab and the queued actions, but ONLY if
the package is compressed.

Weird because the image is OK and extractable; it was originally
compressed too! Other icons (like Wants & Fears) have no apparent issue.

Something to figure out another time, see #54.
