Solutions should have a list of focal points rather than one focus

[ebrahimebrahim]

My implementation of Solution in #116 has a problem: the focus attribute which is one Point should be replaced by a foci or FocalPattern to provide a list of all the focus points. I previously thought that we'd have a Solution for each focus point, but there is actually supposed to be one Solution that includes all focus points.

• Replace focus attribute in Solution by a list of foci (or a FocalPattern from which the list can be generated)
• Update the simulation output xarray in Solution to have an additional axis for focal point index.
• Update the solution analysis code introduced during Port over minimal solution analysis code from matlab #104 to aggregate metrics appropriately over the multiple foci

We want to do this update after the work for #104 is complete
