Add autosplitter for Need for Speed: Carbon Category Extensions

[xicecreaam]

Like for Most Wanted, added a new autosplitter for Need for Speed: Carbon Category Extensions. It is the same file since categories use the same file.

If you are adding or modifying an Auto Splitter, please fill out this checklist:

• ✅ My Auto Splitter does not contain any malicious functionality and I'm entirely responsible for any damages myself. (Any kind of abuse in an Auto Splitter will result in an immediate ban.)
• ✅ I am not replacing an existing Auto Splitter by a different author, or I have received permission from the author to replace the existing Auto Splitter.
• ✅ The Auto Splitter has an open source license that allows anyone to fork and host it.
