prbt-ikfast-manipulator-plugin (here) clash with prbt-ikfast-manipulator-plugin (pilz) #152

I'm not a user of these packages, but during a scripted installation of all released ROS Noetic packages, I ran into the following problem:

Unpacking ros-noetic-prbt-ikfast-manipulator-plugin (0.6.0-1focal.20220515.071829) ...
dpkg: error processing archive /tmp/apt-dpkg-install-P8q7sZ/2909-ros-noetic-prbt-ikfast-manipulator-plugin_0.6.0-1focal.20220515.071829_amd64.deb (--unpack):
 trying to overwrite '/opt/ros/noetic/lib/libprbt_manipulator_moveit_ikfast_plugin.so', which is also in package ros-noetic-moveit-resources-prbt-ikfast-manipulator-plugin 0.8.2-1focal.20220515.071720

note the trying to overwrite '/opt/ros/noetic/lib/libprbt_manipulator_moveit_ikfast_plugin.so', which is also in package ros-noetic-moveit-resources-prbt-ikfast-manipulator-plugin 0.8.2-1focal.20220515.071720 part.

It appears two released packages are trying to install the same file, in the same location.

If users should not try to install both at the same time, perhaps a breaks relation should be declared, or if desirable, a conflicts relation.

I'm guessing it would be easiest to add the breaks or conflicts stanza to the Debian control file for the package here, as, AFAIK, the Pilz repository is unmaintained.
