Possible parallelization of get_descriptors() feature

[zarkoivkovicc]

I would like to get descriptors for a list of molecules, and right now I have to call calculator.get_descriptors(config) for each molecule separately. It would be nice if we could put list[configs] and get a list of descriptors, in a way that each molecule is done in parallel (or in a relatively small amount of batches).

You can do that by adapting the eval config scripts to also write the descriptors.
