Add plot options to support large grids of PSFs

[svank]

We fit lots of PSFs for PUNCH, which makes some of the visualization functions unwieldy. For ArrayPSFTransform.visualize, instead of this:

this PR lets you make this:
psf.visualize(fig_scale=3, edge_trim=15, patch_stride=5)

[svank]

I guess I did break API by removing the old all_patches option. How much should we worry about that?

In the spirit of improving things and helping me not forget what things do, can you add docstrings to the visualization functions?

The CI is complaining about tests. I'm not super worried about testing this, but we could satisfy it. That's secondary.
