Previously, for each HEAD lcluster, it can be either HEAD or PLAIN lcluster to indicate whether the whole pcluster is compressed or not. In this patch, a new HEAD2 head type is introduced to specify another compression algorithm other than the primary algorithm for each compressed file, which can be used for upcoming LZMA compression and LZ4 range dictionary compression for various data patterns. It has been stayed in the EROFS roadmap for years. Complete it now!
