Thank you!

Changes seems fine to me.
However, it seems that you are using a different max line width than the 128 characters specified in the OpenDR coding styles and this produced many unrelated changes:
https://github.com/opendr-eu/opendr/wiki/Coding-Style/#cs101-dont-exceed-128-character-for-line-of-code

Also note that there would also be the README.md file to update accordingly:
https://github.com/opendr-eu/opendr/blob/fdd730c0dcb0218b300e8f29e6a5468c8f8c1fdb/projects/opendr_ws/src/perception/README.md

These changes to the README.md have not been merged to develop yet so it would not be optimal to update the README.md in this branch.
So you could add your changes directly in the #316 branch or create a new PR to merge your changes into #316.

Thank you for the comments, @stefaniapedrazzi.
The line-breaks with end-commas follow the "black" linter style, which does adhere to OpenDR coding style as well. There is no minimum line-break requirement as far as I can see. As to the end-comma, it is increasingly common, as it lets you swap function arguments quickly without risk of forgetting a comma.

As to the README, I'll make sure to update the #316 branch accordingly

Thanks @LukasHedegaard for the node fixes! Changes look good, apart from some minor comments. Unfortunately, i was not able to run the node due to some errors.
