When converting from xml string to js object, & might be double escaped

[chuanqisun]

Describe the bug

const { create } = require('xmlbuilder2');

const result = create(
  `<description>I'm &lt;b&gt;bold&lt;/b&gt;</description>`
).end({ format: 'object' });
console.log(result);
// Actual { description: "I'm &amp;lt;b&amp;gt;bold&amp;lt;/b&amp;gt;" }
// Expected { description: "I'm <b>bold</b>" } Or { description: "I'm &lt;b&gt;bold&lt;/b&gt;" }

To Reproduce
https://stackblitz.com/edit/node-rmf2h7?devtoolsheight=33&file=index.js
run node index.js to produce output

Expected behavior
I might have misunderstood your design. I just thought the parser should either preserve the original string or unescape it.
Double escape the & seems to be strange behavior.

Version:

• node.js: 14.16.0
• xmlbuilder2 2.4.1

Additional context
I'm using your util to build the next major version of an RSS feed reader + generator. I'm following these examples to handle several html encoding scenarios. My primary use case is xml -> json but my tool will also handle feed generation so I really hope I can get the bi-directional conversion working with a single library. Thanks for the high quality work!

Might be related to #82 and #88. Feel free to close this as dupe if they are caused by the same issue.

Yes, this is a duplicate of #82 and #88. An interim fix might be to pass the noDoubleEncoding flag with end if that works for you. I'll fix this in the underlying DOM library: oozcitak/dom#7

The noDoubleEncoding: true option had no effect for me when parsing XML text into Javascript object.
