Initial import of ipyplotly codegen classes into plotly.py

New codegen logic in codegen/
New datatype classes generated into plotly/datatypes/ (These are gitignored)
New validator classes generated into plotly/validators/ (These are gitignored)

Code generation in update_graph_objs.py modified to map Figure, Layout, and Trace types to new plotly/datatypes/ classes. All other classes mapped to raw dicts/lists.
