Second step of RDE encoding refactoring.
Creates a single OutputStream encode RyDE files.
This replaces the 5 OutputStreams that were needed before.
Also removes all the factories that were injected. 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 in each individual OutputStream.
This doesn't yet include a decoder (InputStream). And there's still a lot of overlap between the Ryde and the Ghostryde code. Both of those are left for the next CLs.
