Can't use a configuration file other than pcigale.ini
The pcigale script has an option to indicate which configuration file to use instead of the pcigale.ini file in the work directory: -c. Nevertheless, using this option is not possible because CIGALE expects a pcigale.ini file to be copies in the out directory:
FileNotFoundError: [Errno 2] No such file or directory: 'pcigale.ini'
