Refactor RasterLayer to be based on PropertyLayer in Mesa

[wang-boyu]

What's the problem this feature will solve?

The current implementation of RasterLayer includes copies of some methods from mesa.space.Grid (see #120), making it difficult to maintain.

Describe the solution you'd like

A more related class in Mesa is its recent PropertyLayer (projectmesa/mesa#1898). RasterLayer could inherit from PropertyLayer with added geospatial capabilities.

Additional context

Might also be beneficial to have part of GeoSpace inherit from _PropertyGrid to manage multiple raster layers.

Some related past issues:

• Convenient methods in RasterLayer #91
• Cell aggregation API in raster layer #81

Agree on this! I don't have time to work on it, but I can provide guidance and review.

Also need something similar to projectmesa/mesa#2336 for visualization.
