示例1: ReadChunks
//////////////////
//
// XPK fileformat:
// chunk-based, crunched data in chunks
//
// Chunk format:
// * chunk header
// - 1 byte for chunk type
// - 1 byte for chunk header checksum ?
// - 2 bytes for chunk checksum
// - 2/4 bytes for chunk (compressed) length
// - 2/4 bytes for uncompressed length?
// * chunk data
// - amount of packed data given in chunk header..
//
// Note: chunk header may have different size in different file
// according to flags (if "long" sizes are used for chunks).
//
//
