[svgLib.path] Ignore closepath rounding noise

Relative commands can return to the subpath start with a few bits of floating-point error, causing parse_path to emit a spurious closing line segment.

Use a tight complex comparison before materializing the closing segment and add a regression test for a mathematically closed relative path.
