walking the zip prevents minizip from re-reading the same data repeatedly from the actual backing filesystem. also improves most usages of minizip to allow for >4GB, files altho we probably don't need it

Could you split the >4GB file change into a separate commit from the file scanning change? I'm not familiar with the resource pack code (or minizip as a library) so it's a bit hard to tell what's part of what. |

I think this PR is ready to merge, and I'm not going to spend time to split the commits for review purposes |

Seems fine. |

drops time to "install" https://forums.dolphin-emu.org/Thread-sonic-adventure-2-battle-hd-project-v2-3-june-21-2019 from 9:30 (MINUTES) to 25 seconds (which is still pretty slow imo).
fwiw i tested also with the buffered minizip layer, and there's no speedup. likely because we just read the entire file once. there might be further speedup by decoupling the read + write operations (so it's not serialized), but meh.
