added kwargs to alternate constructor classmethods

These get passed to the init functions.

Example

class Box(Geometry):

    @classmethod
    def from_bounds(cls, rmin: Coordinate, rmax: Coordinate, **kwargs):

        def get_center(pt_min: float, pt_max: float) -> float:
            """Returns center point based on bounds along dimension."""
            if np.isneginf(pt_min) and np.isposinf(pt_max):
                return 0.0
            return (pt_min + pt_max) / 2.0

        center = tuple(get_center(pt_min, pt_max) for pt_min, pt_max in zip(rmin, rmax))
        size = tuple((pt_max - pt_min) for pt_min, pt_max in zip(rmin, rmax))
        return cls(center=center, size=size, **kwargs)

Doing it this way means you can call

sim = Simulation.from_bounds(rmin=(0,0,0), rmax=(1,1,1), grid_size=(.1, .1, .1), run_time=1e-12)

mon = FluxMonitor.from_bounds(rmin=(0,0,0), rmax=(0,1,1), freqs=[1e14])

automatically.

Pretty neat. My only comment is that we're getting a bunch of "black" and "lint" commits in the commit tree. It's not the worst thing in the world but would be nice to squash them before merging to develop.

You can do this manually with the git rebase -i HEAD~2 worfklow (a bit annoying, I don't know if there's a faster way). The github "squash and merge" should only be used if there has been nothing else merged to develop meanwhile, so while it will work for this branch right now, we shouldn't generally use it.

yea good point about the black commits. I'll be more mindful of that moving forward.
