Get all packages in launch files to work

[quantum9Innovation]

Packages with build failures in vehicle.launch.py (in all_seaing_bringup module) are:

• [x] lidar_ld
  • Tracked in [https://github.com/lopsided98/nix-ros-overlay/issues/511], solved in https://github.com/ArcturusNavigation/nix-ros-overlay/commit/14ff69a59a277cbd013a111247d17a23f261e5d6
• [ ] zed_ld
  • Requires setting up the Zed SDK and a bunch of other bloat (see last part of step 3 in https://github.com/ArcturusNavigation/all_seaing_vehicle/wiki/Native-Installation)
• [ ] ublox_ld
  • This should be the easiest to get working; currently all dependencies for this node work but it dies instantly (might be due to a hardware issue so should be tested on the boat to be sure)

[quantum9Innovation]

Issue has been opened here to resolve build issues with lidar_ld (likely improperly packaged in the Nix ROS overlay)

[quantum9Innovation]

ublox_ld issue should be tested for reproducibility on the robot and, if still unresolved, this should take priority over the hardest issue to resolve, which will likely be the zed_ld
