0.1.0a1

Features:

• Adds a (hidden) alias to the main command, bak create, just in case
• bakfiles can now be restored to destinations other than their original location (bak down --help, credit @Serene-Arc)

Fixes and improvements:

• Moves as many filesystem-related functions as possible from os to Pathlib
• Introduces and then patches a bug (hopefully, report if encountered) causing bak down to fail between filesystems
