The SSX scripts currently use me14e_gp9 as a PV for whether we want to abort or not. The bluesky way of doing this is calling abort on the RE, this can be done through blueAPI using blueapi abort. We need to make sure that when the plan is aborted it correctly tidies up, we should do this with the contingency wrapper. We need to make sure the wrapper covers as much of the plan as possible so that if we get an abort when shutter is opening we properly close it. i.e. the chip collect will look something like:

def run_fixed_target_plan(...):
  yield from bpp.contingency_wrapper(
      _run_fixed_target_plan(...), except_plan=run_aborted_plan(...), final_plan=tidy_up_plan(...)
  )

def tidy_up_plan(..):
    # Everything after the wait for the collection to finish

def _run_fixed_target_plan(...):
    # Same as current plan up to when the collection is running then we just have the wait for it to finish
