this fix is a temporary workaround the problem of sequence.par and backward compatibility - Tcl/Tk doesn't know about other than num_cams = 4 case - openptv-python knows about arbitrary num_cams <= 4 and so for 1 camera case - sequence.par is not compatible with the new, smart reading which depends on cpar->num_cams - not sure if the hack should not be used also for 2 or 3 cameras.
