# Description

This MR adds the following:

1. Observations: Adds observations for root state (pos, quat, linear
vel, and angular vel) in the environment frame. Important for assets
such as objects during manipulation.

2. Randomizations: Adds random orientation randomization for assets
(such as objects) and joint position randomization for articulations.

3. Rewards: Adds a termination reward function for specific termination
terms. Needed if terminations are to be weighted individually, for eg,
if successful termination reward should have a different weighting
factor than illegal state termination reward.

Tested for functionality.
