rstnode: basic asset loading and prototype sprite rendering

* restructure assets directory
* implement asset loading and dynamic conversion to sprites
* reload sprites with unique URIs to load at runtime
* provide an updated renderer API to give access to client state
* use new APIs to draw a single node frame on screen
* use colour APIs to dynamically change node frame colour
