guyben 8ec2eaf39c Simplify the RyDE API
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.
