To do this

• Update unitree-ros version to 5dee20c
  • Both of unitree.rosinstall and cross/repo/unitree.repos
• Use go1-robot instead of go1_description-robot in unitreeeus
• Fix misc
  • add go1-simple.l (which is automatically generated during catkin build) to .gitignre
  • add unitree_legged_msgs to the dependencies of unitreeeus
