Creating an XML document then converting to object adds prettification whitespace to JSON

[ethan-xd]

Describe the bug
Creating an XML document from a prettified XML string, with whitespaces and newlines, then converting to a JS object, leaves in /n and whitespaces from the prettification.

To Reproduce
Given part of an XML string:

...
<Point>
  <coordinates>
    144.9690641,-37.8175873,0
  </coordinates>
</Point>
...

...viewing it with:

console.log(JSON.stringify(create(someXMLString).end({ format: 'object' })));

...will show:

...
"Point":{"coordinates":"\n            144.9690641,-37.8175873,0\n          "}
...

Expected behavior
Parsing:

...
<Point>
  <coordinates>
    144.9690641,-37.8175873,0
  </coordinates>
</Point>
...

...should return:

...
"Point":{"coordinates":"144.9690641,-37.8175873,0"}
...
