Giving the user more control in solara visualization of spaces

[quaquel]

The current signature for displaying a space is

def make_space_matplotlib(agent_portrayal=None, propertylayer_portrayal=None):

This gives the user explicit control over the agent_portrayal and the propertylayer_portrayal. However, it also means that the mesa code is making implicit assumptions regarding the attribute to which the space is assigned in the model, and how (depending on the used space class) it is to be visualized. Moreover, it makes space visualization not easily extendable by the user. So, I suggest changing the signature to

def make_space_matplotlib(agent_portrayal=None, propertylayer_portrayal=None, space_portrayal=None, space:str =None):

If space_portrayal is None, we can use the existing if elif structure in SpaceMatplotlib to identify the correct space_portrayal function (probably moved into a separate helper function). Likewise, if space is None, we can fall back on checking model.grid and model.space. This same more fine grained API can also be applied to make_space_altair. @Corvince, @EwoutH, any thoughts?
