WIP on data streamming for sphero.
WIP on sphero data streamming. Fix mask1 and mask2 instance variables.
WIP on data streamming. Add example and update events being emitted.
Added options for setDataStreamming example.
Fix tests by always passing extraParams when instantiating adaptor.
Upd locator example to use setDataStreamming instead of detectLocator, detectLocator() function has been deprecated in favor of setDataStreamming.
Fix test spec conflict.
Use correct spelling of setDataStreaming and update adaptor function to use attrs as masks from the object instance, instead of variables in the function. Remove packet.DLEN validation since now we can have variable length depending of data sources requested.
