* Make Waku node async and gcsafe, hacky
...but the nimbus people are doing it!
* Add skeleton example usage
* Rename example to basic2 and add to Makefile
* Sketch out basic example and qualify imports etc
Loading config to start with.
Quite messy with imports/ambiguous identifiers/qualified names. Probably a
better way with exports (hide implementation details) and fully qualified names
by default?
* Example usage run, public run function
* Sketch out API usage
* Example basic RPC client usage
* waitFor run to compile
* Remove run and gsync markers; adjust example
- Move Waku RPC code from Nimbus + necessary code around it
- Add Waku RPC test which is a copy of the Whisper RPC test
- Some renaming
- Remove nimbus submodule
