Offer to add helper APIs for Path push primitives

[travisgriggs]

It seems kind of inconsistent that Path (the workhorse of any path based drawing library) has a single high level push_arc method, but defers all other types to the lower level SVG path primitives. One of the nice things about using svgwrite, is that for rects and other elements, there is a higherlevel programing centric api to construct the primitive. But Path doesn't get the same love. I would be glad to add a series of "helper" push_line, push_relative_line, etc APIs that hide the grits of SVG path commands, if it had a hope of being integrated. But I noticed that you've said this library is in maintenance. I'm not sure if that qualifies as a "new feature" or something else.

This package is in maintenance mode, no new features will be added, there will be no change of behavior, just bugfixes will be merged.
