Issues #389 - Change Hyperlink Color

[ReimaFrgos]

Adds support for setting the color of a hyperlink text and resolves issues #389

Tested against demo tests and generates all successfully and error free.

No additional user settings. relies on existing text color options. Sample code below:

var slide = pptx.addSlide();

slide.addText(
  [
    { text:'Did You Know?', options:{ fontSize:48, color:pptx.SchemeColor.accent1, breakLine:true } },
    { text:'Hyperlinks', options:{ fontSize:24, breakLine:false, color:'ff0000', hyperlink: { url: "https://github.com/gitbrent/pptxgenjs", tooltip: "Visit Homepage" }
 } },
    { text:' can now be in color', options:{ fontSize:24, color:pptx.SchemeColor.accent6 } }
  ],
  { x:1, y:1, w:'80%', h:1.5, align:'center', fill:pptx.SchemeColor.background2 }
);

slide.addText('Hyperlinks can also be a whole sentence', { fontSize:24, breakLine:false, color:'0fff0f', x:1, y:3, w:'80%', h:1, align:'center', fill:pptx.SchemeColor.background2, 
 hyperlink: { url: "https://github.com/gitbrent/pptxgenjs", tooltip: "Visit Homepage" } }
);

pptx.writeFile('PptxGenJS-Sandbox-'+getTimestamp())
.then(function(fileName){ console.log('Saved! File Name: '+fileName) });

Compatibility Note for Keynote: This will not trigger any errors, but hyperlinks will remain default colors due to functional differences.

This causes an issue with non-colored links - they've now become black instead of the default blue on iOS PPT.

It seems like this was not addressed before the merge?

Is there a way to set all hyperlinks to a specific color? Or do we need to set the color per individual usage basis throughout our slides?
