updated legacy formats.
(BIZ): moved to Adviz folder. (GIZ, GIZ2, BIZ2, PR1): new PC-98 image formats. (DATA, BGM, SED): MyHarvest resource formats. (HTF): compressed image format. (PAK): Mina resource archives. (GCmp): read palette from external resource. (NCG): Nekotaro image format. (BND, TCZ, TSZ): Ponytail Soft PC-98 formats. (NOR): Sophia resource archive. (SDA, PLA): Squadra D resource archives. (UCA): added checks to avoid false positives.
