Log Message:
py-contourpy: update to 1.3.0.

ContourPy 1.3.0 adds new ContourGenerator functions multi_lines
and multi_filled to calculate contour lines and filled contours
over a sequence of levels in a single function call. There are also
new functions to render, convert and dechunk the returns from
multi_lines and multi_filled.

This release adds support for Python 3.13, including free-threaded.
The latter should be considered experimental.

The use of np.nan as the lower_level or upper_level of
ContourGenerator.filled() is no longer permitted.

    multi_lines and multi_filled:
        ContourGenerator.multi_lines and multi_filled (#338, #340, #342, #343)
