Various bug fixes (Mainly RTF). Made it easier to programmatically create pipelines and use custom input sources. Better logging messages around configuration.
Breaking change:
The ``biomedicus run`` command argument for the output directory has switched to an option ``-o``. The correct syntax is now
bash
biomedicus run /path_to/input_dir/ -o /path_to/output_dir/
This is because the option is only used in the case of a serializer (default: json) and if the serializer is set to none the option will not be used.
