Incompatible with franka_ros>0.9.1

[kamiradi]

Hi,

Thanks a lot for open-sourcing this repository, great work.

This is not an issue but more of an observation. I have tested your installation manually against later versions of franka_ros 0.10, 0.10.1 etc.(dockerized mostly). It seems that your code base is incompatible with any franka_ros versions greater than 0.9.1. This is primarily because the folder structure (and urdf tags) of the franka_description has changed after the version, breaking your franka_control.launch file (there is an explicit path towards the panda_arm.urdf).

So you may want to change your readme to instruct users to use any franka_ros between 0.8 and 0.9.1, and the corresponding libfranka.

Thank you for your work.
