Added support for excluding topics via regular expressions

[esteve]

This PR adds --exclude (and -x) as an option to ros2 bag play to exclude topics from being replayed.

I'm not seeing any immediately obvious issues.

@jhdcs thanks for the prompt review. One thing that differs from ros2 bag record --exclude is that this PR accepts multiple regular expressions. Would it be better to keep it consistent and only accept one? It's the same case as with ros2 bag play --regex

[jhdcs]

I feel like keeping it consistent would be best, at least for the moment. If in future we decide that we need to have multiple regular expression support, we can open a new issue at that time and change everything over.

@jhdcs I've updated this PR so that ros2 bag play --exclude only takes one regex, so that it matches the behavior of ros2 bag record --exclude

@jhdcs @MichaelOrlov the CI issues don't seem to be related to the changes in this PR, but I could be wrong. Did they happen in previous PRs?

[MichaelOrlov]

@esteve Yes this is known issue and unrelated to the changes from this PR.
I am sorry I was on vacation and forgot to merge this PR.
