issue #23366.\r\n\r\nThe puppi weight is stored with linear instead of log scale compression to 8 bits.\r\n\r\nThe new compression scheme has improved precision for weights around 0.5, while is was at 10% level before (see https://github.com/cms-sw/cmssw/files/2045014/weight_not_charged_data_MC.pdf)\r\n\r\nThe iorules allow to read files created with older releases within the precision of the old an new compression schemes.\r\n\r\nThe size increase was check with 1000 ttbar events with patMiniAOD_standard_cfg.\r\nbefore this commit\r\npatPackedCandidates_packedPFCandidates__PAT. 136489
