Time to time msg bug

Mentioning (#385)
So what I basically tried was to adapt the rosidl_generator_rs so that it generates publishable rust crates from ros2 message types, as you can see here. that worked reasonably well and since the build worked much better than before, I thought I had solved the problem.

I also read up on the licences of these guys beforehand, so I thought I was on the safe side in this case. Unfortunately, some of these types cannot be deleted from crates.io without further ado. You have to yank them, whereby crates.io first checks whether this dependency is used anywhere. This check is currently running.

@Guelakais thanks for working on this. Could you update the description and the title to reflect what these changes do / fix? We follow this convention for any PR that is submit, it helps us track issues and PRs better. Thanks.

I've noticed you've published a bunch of crates on crates.io that contain the messages, it'd have been nice to notify us beforehand, there's a reason we haven't published them ourselves. This can cause breakages in existing code and conflicting dependencies, please delete them from crates.io

Can you add any of us as maintainers on crates.io so that we can fix this situation if you can't? Thanks

[Guelakais]

Ah, I didn't know that. So the pull request is of course invalid. I thought it might work because of the licences used. Sorry about that.

Don't worry, I know the intention was good. Let me see if it's possible to delete crates from crates.io, in the meantime, could you add me as a maintainer?

[esteve]

crates.io has the policy of not removing crates, they can only be yanked, but the crates are going to be there forever. We'll need to rethink how messages are included during the build to avoid crates.io potentially interfering in the future.

@Guelakais can you add me as a maintainer to the other crates on crates.io? You've only added me to action_msgs, geometry_msgs and lanelet_msgs. I'm going to update their descriptions so that people don't ask us about them.
