The code is ok, but the naming needs to change.

To me the name argparse implies that library implements something
similar to Python argparse. But that isn't what this library does.
It seems limited to just cpu masks. Perhaps cpuparse would be better name
or make it part of a larger implementation of a full library
more like Python argparse.
