Parser bug when trailing space is present after a section name

When running the small cosmo volume simulation with gas using sph and VELOCIraptor and using the attached YAML file the code crashes with: [00000.0] parser.c:parse_value():400: Invalid line:62 ' config_file_name: ./stf_input.cfg', standalone parameter defined with incorrect indentation. This is probably caused by the trailing space after StructureFinding: small_cosmo_volume.yml
