Subject: [PATCH] fix: preserve carriage return characters in CDATA and text
 nodes

Remove the line that globally replaced \r and \r\n with \n in the input XML data.
This replacement was incorrectly converting carriage returns inside CDATA
sections and text nodes, which should be preserved as-is.

The existing TODO comment even suggested removing this line.

Closes #512

- Removed: xmlData.replace(/\r\n?/g, "\n") from OrderedObjParser.js
- Added unit test in cdata_spec.js to verify \r preservation in CDATA and text nodes
- All 315 tests pass with this change
