Astral Chain ripping .DAT help

[Enderfacio]

Hello there! My project is to rip all the characters in Astral Chain. First the 3d models, then maybe one day the textures. 
I extract the .DAT files from the .PKZ with the scirpt found here https://forum.xentax.com/viewtopic.php?f...ad#p155835
But I can´t open the .DAT with Noesis because I don´t know how to uncompress and install the Bayonetta plugins provided here https://github.com/Kerilk/noesis_bayonetta_pc

So, please can anyone here help me uncompress the plugin?
