Also: I think the code can easily be copied for rust binaries to get the same behaviour. |

Allows users to specify the number of threads used (important for HPC/Cluster envs).
There are three ways to do this:
FEOS_MAX_THREADSenv variable.set_num_threads().No matter in which way the pool was initialised, it cannot be changed in the same Python process. Users can use
get_num_threads()to get the number of threads used. Invoking this function will also lazily initialise the thread pool with the default.
