Improve detection for cd/dvd-cops version string

[HeroponRikiBestest]

This removes the content check, moves the NE checks to the NE check section, and adds a PE check for the single currently confirmed section.

One thing I was wondering- what's with the "(Unconfirmed - Please report to us on Github)" parts? They seem pretty confirmed, even being in existing redump entries. Is it supposed to be a placeholder for a safedisc-style version table?

/home/bestest/cdCopsSamples/2002MM/BMM.exe: DVD-Cops (Unconfirmed - Please report to us on Github) 2.01 /home/bestest/cdCopsSamples/2003MM/bmm.exe: DVD-Cops (Unconfirmed - Please report to us on Github) 1,60 /home/bestest/cdCopsSamples/aHugEu/AgentHugo.exe: CD-Cops (Unconfirmed - Please report to us on Github) 1,08 /home/bestest/cdCopsSamples/bib/bib.dll: CD-Cops 1.95 /home/bestest/cdCopsSamples/mofamen/h3blade.exe: CD-Cops (Unconfirmed - Please report to us on Github) 1.72 

Fixes #367

Just because they're in Redump entries doesn't mean that it's been reported or confirmed here in this project. There's no broader plans for a version table or anything of the sort.

Please put this at the bottom to make it more apparent that it's the string version of the byte array.

Implemented all of those. I also noticed and added one last thing, a check for Codefree. Let me know if there are any issues with that.

Edit: attached samples for anyone else who might need them, let me know if these need to be removed.
