* feat: copy existing witgen logic * Separation of `BlobDataConfig` and `BatchDataConfig` (#1214) * blob is the encoded form of batch * fix: bytes_rlc in batch data config is constrained, unit tests OK * Decoder "input region" (#1217) * feat: general gates, tag gates, FHD and FCS * feat: block processing, block header, literals header * fix: degree reduction * feat: add block_idx to decoder's
