[Zint-barcode] Very important feature request!

[Lenuta G. <gav...@gm...>]

Hi there!

First of all I would like to thank you guys for the work you put in this
awesome project which by far has no alternatives, but today when I was
using Zint I've noticed that for some reason it lacks .JPG format support,
which to be fair I didn't expect it would; I didn't needed it till today
but always thought it would be there by design, since there are so many
other less popular raster image formats, but not the most popular one, the
.JPG.

*TLDR:*
Please add the .JPG format!
