rr_rover_zero_driver missing rospy dependency

[tfoote]

rr_rover_zero_driver is missing a dependency on rospy

This is failing debian package builds

http://build.ros.org/view/Kbin_uX64/job/Kbin_uX64__rr_rover_zero_driver__ubuntu_xenial_amd64__binary/79/console

16:18:49 -- Could not find the required component 'rospy'. The following CMake error indicates that you either need to install the package with the same name or change your environment so that it can be found.
16:18:49 CMake Error at /opt/ros/kinetic/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
16:18:49   Could not find a package configuration file provided by "rospy" with any of
16:18:49   the following names:
16:18:49 
16:18:49     rospyConfig.cmake
16:18:49     rospy-config.cmake
16:18:49 
16:18:49   Add the installation prefix of "rospy" to CMAKE_PREFIX_PATH or set
16:18:49   "rospy_DIR" to a directory containing one of the above files.  If "rospy"
16:18:49   provides a separate development package or SDK, be sure it has been
16:18:49   installed.

I see that the CircleCI jobs are failing too, but I can't seem to get public access to the results to review.

It's also an issue for the melodic branch: http://build.ros.org/job/Mbin_uB64__rr_rover_zero_driver__ubuntu_bionic_amd64__binary/

This is causing a regression of rr_openrover_stack which the new release depends on this new package.

This is the one regression in the upcoming sync here: https://discourse.ros.org/t/preparing-for-kinetic-sync-2020-06-10/14614

Dependency issues appear to be resolved in latest release 1.0.1 and 1.1.1.

Apologies for any disruptions.
