Allows use of Path objects when reading env from the filesystem.

Allows use of read_env(BASE_DIR / '.env') instead of read_env(os.path.join(BASE_DIR, '.env'))

[jerivas]

In the meantime, for anyone looking to use Path without having to import os you can do str(BASE_DIR / '.env') to get the path that read_env will accept

This is resolved in develop branch. Thank you for the patch, and for helping us make django-environ better. And I am sorry about the delay.
