lrmate200ic: add experimental support for LR Mate 200iC/5F. For ros-industrial/fanuc#111.
lrmate200ic: clarify listing of supported variants. Fix ros-industrial/fanuc#111.

Cleanroom and food variants are identical to their base versions,
at least wrt joint position and velocity limits.
lrmate200ic5f: fix link_4 length.

Misread spec sheet. Link was 0.5mm too short. This caused the Cartesian pose
reported for tool0 to be incorrect.
lrmate200ic: clarify notation used in supported variant list.
lrmate200ic5f: add MoveIt IKFast plugin. Fix ros-industrial/fanuc#130.

This is an old-style IKFast plugin, functionality-wise identical to the others in
the LR Mate 200iC MoveIt plugins package. This does not include the recently merged
ik-search optimisations in moveit_ikfast.
