 * @brief Utility library for file bundling
 *
 * @details This library implements a simple in-memory archive format which
 * can be used to package and compress assets for faster loading, as well as a
 * generic LZ77 compressor and matching decompressor. Two archive formats are
 * supported, one uncompressed (.QLP) and one with individually compressed
 * entries (.LZP).
 *
 * This header provides functions to parse .QLP archives and retrieve pointers
 * to their contents after they have been loaded into memory.
