Add string representations for procedures classes

[jacobdeery]

We haven't defined __str__ methods for Action, Transition, Step, Procedure, or any of the condition classes, which means that when we print them we get things like this:

<topside.procedures.conditions.GreaterEqual object at 0x0000024844702688>

Action(component='c1', state='open')

ProcedureStep(step_id='s1', action=None, conditions={<topside.procedures.conditions.Immediate object at 0x0000024815FC2748>: Transition(procedure='p1', step='s2')})

Procedure(procedure_id='p1', steps={'s1': ProcedureStep(step_id='s1', action=None, conditions={<topside.procedures.conditions.Immediate object at 0x0000024815FC2748>: Transition(procedure='p1', step='s2')}), 's2': ProcedureStep(step_id='s2', action=Action(component='c1', state='open'), conditions={<topside.procedures.conditions.Immediate object at 0x0000024844DA0448>: Transition(procedure='p1', step='s3')}), 's3': ProcedureStep(step_id='s3', action=Action(component='c1', state='closed'), conditions={})})

This isn't wrong, but when we want to add logging it will definitely be more convenient to have string representations so that it's easier to read.

I want to work on this issue, can you assign it to me?

Hello @Aditya1001001 - typically we only assign issues to Waterloo Rocketry team members. Are you a member of the team?

@jacobdeery I'm afraid I'm not a member of the team. Can you still assign it to me?

@Aditya1001001 - Right now Topside is still in its early stages and we would like to save these issues as opportunities for newer team members to become familiar with the project. Thank you for your interest, though!

@jacobdeery that's a bit disappointing. I'll just watch the repo for now.
