simple-xml XXE vulnerability

[Matthew-X]

Hi, I wanted to implement this tool into my project, but it turns out that simple-xml has an XXE vulnerability. Would it be possible to replace this library with another? There is a fork from the simple-xml that presumably does not has XXE vulnerability in it, it's called simple-xml-safe (link: https://github.com/carrotsearch/simplexml-safe ). Could you implement it into your project or could I try do that and later create a PR to merge into your branch? Thank you.
