All Rack-It loader variants supported in TAPClean now

Today, after rewriting the code for this format in order to extract loader parameters on a per tape basis (similarly to what happens for Cyberload), I also added support for the only known variant used in a few titles.

In total, there are 13 Commodore 64 tape dumps that can now be automatically tested and archived for preservation 🙂

Thanks go to Mason for making the tape dumps available and Peepo for setting up the FTP “exchange” server!
