  Improvements to Nichols chart plotting

Clip closed-loop contour labels.

Add labels for constant closed-loop phase contours.

Use smaller of data or view extents when deciding on how big, in
phase, a chart to create.

Use more uniformly spaced closed-loop phase contours, and use more
widely-spaced contours when phase extent is large.

Add optional `ax` argument, for axes to add grid to.
