da.polyfitandxr.polyvaland is usingxr.core.missing.get_clean_interp_indexin order to get the fitting coordinate. However, this method is stricter than what polyfit needs: as innumpy.polyfit, non-unique and non-monotonic indexes are acceptable. This PR adds astrictkeyword argument toget_clean_interp_indexso we can skip the uniqueness and monotony tests.ds.polyfitandxr.polyvalwere modified to use that keyword. I only added tests forget_clean_interp_index, could add more forpolyfitif requested.
