Replace GeoSir scheduler with AgentSet functionality

[EwoutH]

Currently the GeoSir model has interesting scheduling behavior, where it looks like the Agents are added multiple times to a base schedulers, with all Agents first being added, and then their neighbours again:

mesa-examples/gis/geo_sir/model.py

Line 32 in 2c05149

self.schedule = mesa.time.BaseScheduler(self)

mesa-examples/gis/geo_sir/model.py

Lines 84 to 90 in 2c05149

	self.schedule.add(this_person)
	# Add the neighbourhood agents to schedule AFTER person agents,
	# to allow them to update their color by using BaseScheduler
	for agent in neighbourhood_agents:
	self.schedule.add(agent)

mesa-examples/gis/geo_sir/model.py

Line 107 in 2c05149

self.schedule.step()

The schedulers are deprecated (see projectmesa/mesa#2306), so we would like to replace the BaseScheduler with AgentSet.do() operations (as of the Migration guide).

@glicerico, if I'm correct you originally wrote this model. Could you explain exactly what's happening? And would you be interested in updating the example?

@EwoutH i highly doubt I wrote this model, unless my memory has totally forgotten it, hehe... but I also don't appear in the list of contributors.

[EwoutH]

Apparently you did :)

hahaha seems like it was a mem segfault... :P I used this for a short time only.

So, i doubt I can easily help with migration at this point if I didn't even remember I wrote it, sorry!
