Breaking change in 4.1 - returns instance of Illuminate\Support\HtmlString #205

I noticed after updating from 4.0 to 4.1, the Generator now returns an instance of Illuminate\Support\HtmlString rather than a string.

Luckily the "fix" is simply casting this to a string:

$var = (string)QrCode::format('svg')->margin(0)->size(200)->generate($inlineUrl);

Hopefully this helps anybody experiencing this issue after updating.
