We modified the patch writer to have the capability to produce the smallest patch if multiple compressors are given. This type is supported for bsdf2 format only. Example usage: bsdiff --format=bsdf2 --type=bz2:brotli <src_file> <tgt_file> <patch_file> Test: diff & patch an apk file Change-Id: Icd4322f21975b82c5ee09f8feb9321f52c9813a4
