Descriptive summary

desired_phase_plan_generator has a method called convert_spat_to_dpp which converts the movement_event list in spat to a desired_phase_plan. This method will go through all possible movement groups and check if the movement_event list in spat contains green movement_states with the same start and end time for all signal groups included in a movement group. Now, if a movement group contains more than 1 signal group (e.g., movement group 1: [signal group 1, signal group 5]), but the movement_event list in spat has green movement_states for only one of the signal groups (e.g., signal group 1 is green from timestamp x to timestamp y, but signal group 5 is not green from timestamp x to timestamp y), then the convert_spat_to_dpp method will not add this movement group to the converted desired plan. This is the intended behavior, but the method does not log any statement to inform the operator about this case or throws any exception. This issue is created to add log statement and exception for this case.
