Subject: [PATCH] src/figures/cantilever-data: Modernize print statements

Old                 New
===============     ================
print >> x, ...     x.write(...)
print ...           print(...)
'%s' % (...)        '{}'.format(...)
===============     ================

The old `print >> ` syntax wasn't Python 3 compliant.
