@Karsten1987 does this PR need CI to merge?
Dpr and Epr are failing due to unrelated changes.

[zmichaels11]

All tests passed on Linux CI, going to kick off CI for other OS's

[zmichaels11]

I ran CI with packaging on all OS.
Linux and Linux ARM64 are running properly. They're marked unstable due to a deprecation warning in ros1_bridge: "Package 'actionlib_msgs' is deprecated"

macOS packaging reports as passing, however it stopped after building the underlay.
Windows packagin reports as unstable and didn't finish building the underlay. (It didn't `packages-skip ros1_bridge like Linux/Linux ARM64 did)

@Karsten1987 what do you think should be done?

[Karsten1987]

this looks good to me. For specifically this plugin, we don't have to care too much for MacOS and Windows as I doubt they every come out clean.

For the linux ones, the tests for the bag_v2 run and pass, so that's really what matters here IMO.
