Description

This PR provides a reference implementation for the universal radar messages explained in the previous link

The currently published PointCloud2 works as the universal radar detection implementation (we want the least number of restrictions over it so it can be expanded and can fully use each radars' features if needed, although autoware does not have a plan for this at the moment).

A new universal radar object message is used, which can model all of the radars we know of.

A new radar info message publishes information about each of the radar fields, such as if it is really filled, its ranges, and resolution.

Review Procedure

The new topics comply with the previous interface (I compared the original topics and the proposed ones with ros2 topic echo and confirmed that they worked as expected).
