Dat.parser.py not working with numpy >1.19 (fixed it by replacing "np.object" with "object")

(fthis is my first bug-report, I'm sorry if I missed something)

DAT_parser.py uses np.object three times, which is not supported anymore by numpy 1.20 and above. The error message suggests to replace np.object with object, which worked for me.
