+I updated the copyright statements to match those on the WTFPL FAQ, completed
+the flags for the ST2 and ST3 in KFloppyA.HH, updating the copyright notice

-I had a brain fart and forgot to revert the hard-coded DMA buffer address, as pointed out by TheTinkerer on the TOS Discord.
-I went ahead and uncommented the stuff for splitting up the address, and fixed the base address I/O writes.
-If you have installed the driver, just replace NewFloppy.HC and recompile the kernel; you should be good after that.
