Support more geometry types for alerts

[EvanHahn]

Point is currently the only supported geometry type:

comapeo-cloud/src/schemas.js

Lines 71 to 74 in d6ab531

	geometry: Type.Object({
	type: Type.Literal('Point'),
	coordinates: Type.Tuple([longitude, latitude]),
	}),

We want to add support for more types.
