Missing license for this repository

[JNPauli]

Hello, my name is Janos Pauli. I opened this issue concerning the license and thus usage rights of this repository. Within a research project I'm conducting during my master's program I would like to conduct an ML analysis focusing on some of the imagenet stimuli and their respective category. As I thus need the stimuli corresponding classes, I would like to utilize the resources provided in this repository. However, I was not able to find its license and therefore usage rights/permissions and wanted to ask if this noted somewhere and if not, if the respective information could be added? I'm truly sorry if I missed something obvious and would like to thank you for this great resources.
Best,
Janos :)
