Update data of existing chart

[Duncan Sample]

I've got an existing set of slides which have a couple of charts and a couple of tables on them. I'd like to be able to update the Excel data which sits behind the charts, is that possible? I couldn't see a getChart function.

I'd like to update the data in the tables too. The tables aren't Excel as far as I know, they're just PowerPoint's 'Insert Table' tables. I don't mind tidying the slide up manually if there gets to be too many rows, but I'd like to be able to start with what I've created within PowerPoint, rather than having to recreate it all from scratch.

@dsample - For editing charts from an externally loaded pptx, I'm afraid this isn't supported at the moment with the nodejs-pptx package. However, we do have it in our backlog of TODO items to eventually support this.

@dsample PRs welcomed too :-)
