Add the new Event Data to json format Algorithms

Most changes are on the standalone.py file. Basically I add the newly created C++ algorithms that are used to retrieve LHCb event data and transform them into .json format. To be used in the Phoenix Framework. https://github.com/HSF/phoenix (New LHCb web event and geometry display)

Depends on LHCb!3241 (merged), Rec!2537 (merged) and gaudi/Gaudi!1278 (merged)
