"Missing Arguments" error when running simple_mission_2 (or _1)

[yeff-fresh]

Hi Clearpath --

I'm using the latest (main) clearpath_onav_examples and running them against a CP Husky running OutdoorNav v0.11. I cloned the repository earlier today (Wed Feb 21)

When trying to run simple_mission_2, I got an error (this also happened with simple_mission_1):

Traceback (most recent call last):
File "/home/seymour/workspace/src/clearpath_onav_examples/clearpath_onav_api_examples/scripts/simple_mission_2", line 43, in
if SimpleMission2().run():
File "/home/seymour/workspace/src/clearpath_onav_examples/clearpath_onav_api_examples/scripts/simple_mission_2", line 29, in init
self.mission = Mission("Mission 2", "uuid-mission-2", waypoints)
TypeError: init() missing 2 required positional arguments: 'on_start_tasks' and 'on_stop_tasks'

Looking at the definition of Mission in clearnav_onav_api_examples_lib/src/mission.py, I see that the class constructor does want parameters on_start_tasks and on_stop_tasks and does not provide a default for them.

Changing simple_mission_2 to define the variables and add to the constructor solved the problem:

    on_start_tasks = []
    on_stop_tasks = []
    self.mission = Mission("Mission 2", "uuid-mission-2", waypoints, on_start_tasks, on_stop_tasks)

Thought you'd want to know!

(ETA - Looks like all the Mission() constructor calls in the examples have this issue. Probably easier to add defaults to the mission constructor in mission.py. I did this and it works great).
