Provide a convenience AnalysisHandler::getYodaAOs() method
Via @lcorpe :
"From the Gambit/Yoda/CONTUR meeting the other week, we discussed the idea of an API for transferring data types directly, rather than write in/out to text, for uses such as Gambit..."
Indeed. I didn't realise we didn't have a simple way anymore. The logic to do it is embedded in the getRivetAOs() function, but is seriously messy and maybe not even quite achievable from outside. I'll wrap this up into a separate function with an optional flag to skip the RAW histos.
