plot_probe_group -> plot_probegroup

[zm711]

In regards to trying to get more api regularity the object is called a probegroup we don't ever write it as a probe_group. So I would say that to be consistent the plottting function should be plot_probegroup.

If we want full coverage I can add one test where we run the deprecated function.

@alejoe91 this is my bonus api fix, but I'm associating it with this hackathon ;)
