Ncplot

This is a minor release that deals with some dependency issues.

This release makes a small improvement to how projections are handled.

This is a minor release. Previously passing hvplot's clim argument to `view` did not work unless `autoscale` was set to False. It now works automatically.

This is a minor release. The only change is some version pinning to get around a dependency breaking with recent versions of jinja2. Everything else is unaffected.

This release makes some improvements to how non-CF compliant files are handled. In cases where files are not CF-compliant and ncplot internal xarray cannot decode the coordinates, ncplot should now be able to make a reasonable assumption about which dimension should be converted to a coordinate.

This release removes cartopy as an explicit dependency. Cartopy is used for projecting data, but often it will not import after a new install. This is potentially off putting for new users of ncplot and nctoolkit. So ncplot will now use hvplot defaults when cartopy is not importable and it will suggest installing cartopy.
