Numba caching prevents definition of new functions

[DavidLP]

One cannot define new end_of_custer or end_of_event functions, when the interface data stay the same. The reason is, that caching is activated for: https://github.com/SiLab-Bonn/pixel_clusterizer/blob/master/pixel_clusterizer/cluster_functions.py#L167

There is no simple way to remove exisiting caches: https://stackoverflow.com/questions/44131691/how-to-clear-cache-or-force-recompilation-in-numba

Solutions: Clear cache manually when set_end_of_cluster_function or set_end_of_event_function are called

Thanks for pointing this out! :) I think this is exactly what we observed a few times already @cbespin, no?

[cbespin]

Yes, I found no other way than clearing the cache manually. IIRC, it is the __pycache__ folder in the numba installation directory, not the one from pixel_clusterizer. That should be checked a second time before this remains the current solution.

Ahh yes. I was already wondering where the cache folder is. It was not the one where the script is. At least not when using Windows.
