Add vectorio: for drawing shapes vectorio builds on m4 express feather Concrete shapes are composed into a VectorShape which is put into a displayio Group for display. VectorShape provides transpose and x/y positioning for shape implementations. Included Shapes: * Circle - A radius; Circle is positioned at its axis in the VectorShape. - You can freely modify the radius to grow and shrink the circle in-place. * Polygon - An ordered list of points. - Beteween each successive point an edge is inferred. A final edge closing the shape is inferred between the last point and the first point. - You can modify the points in a Polygon. The points' coordinate system is relative to (0, 0) so if you'd like a top-center justified 10x20 rectangle you can do points [(-5, 0), (5, 0), (5, 20), (0, 20)] and your VectorShape x and y properties will position the rectangle relative to its top center point * Rectangle A width and a height.

vectorio: add draw protocol * Removes VectorShape from user python interactions * Re-integrates vectorio with displayio behind draw protocol implementations * Implements draw protocol with VectorShape * Composes VectorShape behaviors into Rectangle, Circle and Polygon * Fixes terrible pixel garbage being left behind * Improves redraw performance (heuristically) by tracking dirty area separately from current area. Known Issues: It does not work with transposed views.
