First step of RDE encoding refactoring.
Creates a single InputStream (OutputStream) to decode (encode) Ghostryde files.
This replaces the 3 InputStreams (OutputStreams) that were needed before.
Also removes a lot of classes, and removes the "injection" of the Ghostryde
class. It's an encoding, there's no point in injecting it.
Finally, removed the buffer-size configuration and replaced with a static final
const value. It's just a buffer size - it doesn't actually affect much. There
are much more "important" fields that weren't configured (such as the
compression algorithm and whether or not to do integrity checks)
