Bug description

Unable to load some SVG files, such as https://commons.wikimedia.org/wiki/File:Aiga_departingflights.svg you get something similar to:

ArrayIndexOutOfBoundsException: Index 43 out of bounds for length 43

Steps to reproduce this

1. Launch PDE, create a sketch, download https://commons.wikimedia.org/wiki/File:Aiga_departingflights.svg and add it to the data folder of your sketch.

2. Run the snippet below:

void setup(){
  size(500, 500);
  PShape svg = loadShape("Aiga_departingflights.svg");
  shape(svg);  // will crash before this line... 
}

Additional context

This looks a bit like #750 but the "SVG path notation parsing issue" that causes it to fail seems different.

The provided failing SVG looks like this:

<svg xmlns="http://www.w3.org/2000/svg" version="1.0" viewBox="0 0 29 29">
<path d="m0 6 3-2 15 4 7-7a2 2 0 013 3l-7 7 4 15-2 3-7-13-5 5v4l-2 2-2-5-5-2 2-2h4l5-5z"/>
</svg>

If you scale it a bit on Inkscape you get a different path notation and it works fine:

<svg xmlns="http://www.w3.org/2000/svg" version="1.0" viewBox="0 0 29 29">
<path d="m 0,5.9994379 2.9997,-1.9998 14.9985,3.9996 6.9993,-6.99930004 a 2.1211082,2.1211082 0 0 1 2.9997,2.99970004 l -6.9993,6.9993001 3.9996,14.9985 -1.9998,2.9997 -6.9993,-12.9987 -4.9995,4.9995 v 3.9996 l -1.9998,1.9998 -1.9998,-4.9995 -4.9995,-1.9998 1.9998,-1.9998 h 3.9996 l 4.9995,-4.9995 z"/>
