Issues with latest version of dm_control

[vandrw]

Problem
The latest version of dm_control does not seem compatible with this project. When running the provided bash script, the program crashes.

Fix (temporary)
We managed to temporarily fix this issue by downgrading to dm-control==0.0.364896371 in requirements.txt.

Stdout:

[/tmpfs/src/git/dm_robotics-kokoro/cpp/support/include/dm_robotics/support/logging.h:
Fatal Python error: Aborted

Hello,

Thanks for pointing this out. We've fixed the issue by freezing the dependency version. Everything should work now
