WITCH formal release v1.0.2

All changes can be found in CHANGELOG.

1. Added an option to bypass the initial config setup step. Use -y or --bypass-setup in your command line running WITCH to avoid being asked where to generate the config directory (will default to ~/.witch_msa).
   • For example: running witch.py -y -i [sequence files] for the first time will directly set up the WITCH configuration file and align the input sequences.
   • For any more runs, including -y is not required since the config file has been correctly set up.
