Make figures loaded from experiment db viewable in notebook

[chriseclectic]

What is the expected behavior?

If you load a saved experiment from the database trying to view figures returns a bytes object for the loaded SVG file. This can be made viewable by using Ipython.display.SVG so it might be nice to do this automatically in the DbExperimentDataV1.figure function along lines of:

# during file imports
try:
    from IPython.display import SVG
    display_svg = True
except ImportError:
    display_svg = False

# at end of `DbExperimentData.figure` method
if isinstance(figure_data, bytes) and display_svg:
    return SVG(figure_data)
return figure_data
