Fixed bug for directories containing spaces

[vishneshjr]

Motivation and Context

Previously the code would not work for directories containing spaces (due to a split function being called). This has now been fixed.

For example, if you try to run the command:
python -m habitat_sim.utils.datasets_download --uids habitat_test_scenes --data-path ./Data" from the directory: "/Users/vishnesh/Master/Sample Folder With Spaces", you get the following error.

How Has This Been Tested

This has been tested by reviewing how the path is split and by running the same command python -m habitat_sim.utils.datasets_download --uids habitat_test_scenes --data-path ./Data" without any errors.

Sorry for the review delay.

No problem! I think I saw the same issue in some other places. I'll let you know if I find it elsewhere.
