ros-noetic driver for serow + small changes

[MichaelMarav]

Description

• Added a ros driver for serow (single node) subs to topics and calls the serow filter. Publishes the base state under /serow/base_estimate
• added the remapper for the valk .bag that corrects the frames (.bag is to large to push)
• added valk json (non tuned)
• Removed redundant if (ft.has_value) from serow.cpp (if it doesn't the function returns at the the start)
• Added check for correct frames in the wrench measurement
• added vs code, devel and build folders to gitignore
• split ros1 and ros2 into two workspaces: ros_ws and ros2_ws
