SVG Import - some paths fail to import

Hi,

I noticed makerJs sometimes failed to import some SVG paths generated by other libraries.

M 0 0 L 10 0 will import ok.
M 0 0 10 0 will fail to import.

The SVG Move Path command spec mentions:

Move the begining of the next subpath to the coordinate x,y. All subsequente pair of coordinates are considered implicite absolute LineTo (L) command.

I suspect the SVG Importer is not handling this part of the spec.

Simple demo below (can copy and paste into https://maker.js.org/playground):

var makerjs = require('makerjs');

// Draw a square from origin 0,0 with sides of 10 units.
// Equivalent to:
// <svg xmlns="http://www.w3.org/2000/svg">
//     <path stroke="red" fill="none" d="M 0 0 L 10 0"/>
//     <path stroke="red" fill="none" d="M 10,0 L 10,10"/>
//     <path stroke="red" fill="none" d="M 10 10 0 10"/>
//     <path stroke="red" fill="none" d="M 0,10 0,0"/>
// </svg>

var svgTestPaths = 
{
    path1: "M 0 0 L 10 0",    // Top    (ok)
    path2: "M 10,0 L 10,10",  // Right  (ok) 
    path3: "M 10 10 0 10",    // Bottom (failed)
    path4: "M 0,10 0,0"       // Left   (failed)
};

this.models = 
{
    path1: makerjs.importer.fromSVGPathData(svgTestPaths.path1),
    path2: makerjs.importer.fromSVGPathData(svgTestPaths.path2),
    path3: makerjs.importer.fromSVGPathData(svgTestPaths.path3),
    path4: makerjs.importer.fromSVGPathData(svgTestPaths.path4)
};

this.notes = 
[
	'# SVG path import test',
	'Draw four sides of a square using various SVG Path syntax. ' + 
    'Note the bottom and left paths fail to import'
].join('\n');

Start at the makerjs.importer.fromSVGPathData entry point and trace how SVG move-path coordinates are parsed. Use the provided path3 and path4 reproduction alongside the explicit-L examples. Done means repeated coordinate pairs after an M command import as line segments and both shorthand paths produce the expected square sides.
