adding h1 artifacts (kscalelabs#42)

* higher velocity works with tgs engine

* h1 loading into env

* import fixes

* restored joints.py

* robot_fixed is correct now

* fixing merge

* lint

* more lint

* more lint

* cleanup h1 artifacts

+"""Defines a more Pythonic interface for specifying the joint names.
+
+The best way to re-generate this snippet for a new robot is to use the
+`sim/scripts/print_joints.py` script. This script will print out a hierarchical
+tree of the various joint names in the robot.
