Flopy

Provide interim support for Matplotlib 3.8+, which [changed the way contours are represented](https://github.com/matplotlib/matplotlib/pull/25247/files#diff-918125f8b0a3d8085b15096d948f8e005d5dc938ea54501ba3c1f7a36ad74f7f) and broke `export_contours()` and `export_contourf()`.

**Note**: with MPL 3.8+, FloPy can no longer export interior polygons (i.e. holes) for filled contours. This is a backwards-incompatible change, and could be considered worthy of a major release — with some compunction, FloPy follows MPL's example here, and this remains a patch release. A future version may [reimplement contour export and restore support for interior polygons](https://github.com/modflowpy/flopy/issues/1973). In the meantime, users requiring interior polygons should pin MPL below 3.8.
