rendered.h / renderer.cpp file location

[jeroenvermeulen]

@gemu2015 Would it maybe be a good idea to move the renderer.h and renderer.cpp to a more generic location?
I think it is kind of messy it is inside the esp-epaper-29-ws-20171230-gemu-1.1/src dir but it is used in a growing number of drivers.
I am working on one extra driver.
Maybe I can send a PR to move the Renderer files?

Yes this would be a good idea to split this folder into 3. (renderer, epaper29,epaper42) !
No problems, of course you can.
