Can't override margin with 0

[scottmtraver]

PptxGenJS/dist/pptxgen.js

Line 2477 in eefae75

opts.margin = opts.marginPt || opts.margin || 0.5;

One cannot override options margin with a 0 because it is JS 'falsey' and the 0.5 is the result of this line. I will fix it soon when I get the chance.

Hi @scottmtraver ,

Thanks for reporting this!

I've fixed the issue in both addTable() and addSlidesForTable().
