clean and speed up doctesting of bessel.py

[rwst]

70% of long doctesting concerns four complex plots in bessel.py. Setting plot_points=10 will probably not affect doctest quality but would be much faster. Even if done with image output there seems no difference in quality of the produced images.

This ticket applies all cleanup changes of #16023 and #16173 that are in bessel.py, as well as setting plot_points=10. It results in a reduction of long doctesting time by 80%.

You should use :trac:`10251`

Do you still need long time in this case? Also, perhaps a # comment about how we speed it up with fewer plot_points would help readers unfamiliar with that function.

By the way, I find that the different regions differentiate themselves better with plot_points=20...

All done, and included the string "Set plot_points to a higher value to get more detail"

I cannot see a commit from #16173 that is not included in my branch of this ticket, and I just pushed it, so it must be on trac too.

Okay, I got beta0 working and the two changes specific to this ticket are fine and I already checked they look good before. Nice.
