You run the script from the command prompt. Open command prompt and type python path\to\daesplitter.py path\to\your\model.dae. Make sure Python is installed and added to your PATH (you can check by running just python and seeing if it starts), and that the paths are correct.
However, if you want to get it into Blender there's an easier way you can try first. Convert the nsbmd file to a .glb instead of a .dae by adding the flag --format=glb (or just -fglb for short) when you run apicula convert. Then make sure you have a recent version of Blender (preferably the latest, but 2.83 at the least) and you can import the .glb into Blender with File > Import > glTF 2.0. The glTF importer actually imports multiple animations!
The first animation plays by default. To switch animations, open the NLA Editor in Blender and click the star button next to the one you want to play.
