    With the new 2.8.2 K4PC, Amazon introduced new key system that uses encrypted keys that are never in cleartext in memory. As such, I was forced to step one step closer to the gaping, quivering Analog hole.

    Introducing new tool, KFXArchiver (KFXArchiver282), which uses some more of the code from DeDRM plugin to create decrypted book archives. The archives have extension KFX-ZIP, but are decrypted. One needs KFX Input Calibre plugin installed. Then on import, they should become a single KFX file. In theory, DeDRM plugin does not need to be installed (for KFX), but why not keep it for other formats and older books?

    Usage is similar to KFXKeyExtractor282, but it produces books instead of keyfile.

    Example:
    KFXArchiver282.exe "C:\Users\User\Documents\My Kindle Content" output_folder output.k4i

    Note that output folder must exist, tool is not going to make one. When in doubt, might as well use "." (current folder)
    k4i file should be like before, unless I forgot something again.

    Note: KFXKeyExtractor282 might still work for some books, as it seems like the settings are not stable yet on Amazon servers.
    Note: Both of the *282 executables should all work on 2.8.0, 2.8.1 and 2.8.2, but not other versions.

    As usual, no guarantee, what works for me (and some others) might not work for a particular setup other people might have.

    Yes, Extractor28 and Extractor282 are the same file.
    Edit: 2.8.2 and 2.8.1 use different key format so it does not quite work.

    Synchronized my fork with upstream so it would serve as stopgap release until noDRM finishes bugfixing and releases proper version. Version number arbitrary. Not guaranteed to work.
