// Convert proprietary Blizzard formats to wowee open formats as a
// post-extraction pass. Each emit*() reads a single file from disk and
// writes the open-format equivalent SIDE-BY-SIDE — the original file is
// left untouched so private servers (AzerothCore/TrinityCore) that
// expect .blp/.dbc/.m2/.wmo continue to work unchanged.
//
// Naming: foo.blp → foo.png, foo.dbc → foo.json, foo.m2 → foo.wom,
//         foo.wmo → foo.wob.
