Title: Allow for coord grid charts to reset on clicking in deselected area

coordinate grid charts currently don't reset the filter if one clicks on deselected area, because brushing(g) doesn't check _brush.empty() before setting the filter to an extent that may be empty, e.g. [15, 15].

Fantastic library, btw! So glad you made it!
