ARSCLib does not handle invalid filenames during APK resource decoding on Windows

[wchill]

Original issue: MorpheApp/morphe-patcher#155

It was determined in that issue that the APK may contain resources that resolve to invalid filenames on Windows. This causes file extraction to fail.

Fixing this might require maintaining some extra mapping information (in the path-map.json, maybe?) that maps the real filenames to Windows-compatible ones.

Alternative option might be to prefix paths with \\?\ on Windows, though I don't know how well this would work in practice.
