Update csv4d2ifc.py (#4935)

Please correct me if I am wrong:

while trying to create relationships I saw that in def create_rel_sequence (line 194) there is a parameter missing which should reflect the "rel_type", otherwise and according to "assign_sequence.py" the sequence_type remains 
def assign_sequence(
    file: ifcopenshell.file,
    relating_process: ifcopenshell.entity_instance,
    related_process: ifcopenshell.entity_instance,
    sequence_type: str = "FINISH_START",
