This commit decrypts most of the encrypted CodeBreaker cheat codes into
their plain format. I manually fixed some games that had both plain and
encrypted codes, causing some of them not to work.
The advantage of having all codes in plain format is that it allows for
users to add their codes (appending the file). Encryption prevents this
since the cheat decoder tries to decrypt unconditionally.
Added a tiny python script that assists in decoding these cheatcodes. It
is not very smart so it might decrypt stuff that's already decrypted
depending on the order of the cheats in the file.
I manually eveyballed all the codes and ran some sanity checks on them
to the point I trust most of the changes here. Some codes were already
broken so I hopefully mend more things that I'm breaking with this
change.
Sorry for the whitespace cleanup! That's the script rewriting the files
cleanly
- I removed unused `import`s.
- I removed a `pass` statement that is unnecessary because a `print` statement follows it.

This is a quick-and-dirty script to generate a dat file from MAME XML
which picks a single unique ROM for each machine where an unambiguous
choice is possible.
