relax torch 2.4.0 hard pin

[romeokienzler]

pinning torch to 2.4.0 causes some problems when
a) co-installing with TerraTorch
b) using python 3.13

Please consider relaxing the strict pin from to something like:

torch>=2.0 if possible

for a) I have a workaround (installing torch 2.4.0 first)
for b) it breaks the tests
