Description

Some error were being printed as cerr which in some cases is not captured by the logging system.
Additionally, in ROS, stoud and stderr is sometimed not flushed so manual flushes are required.
Since we do not excessively flush, it should not be a problem

Since PR #233, Nebula provides a built-in way to ensure that ROS logging functions are used when launched using ROS.
This logger has already been integrated for the Hesai HW interface in #232, and I took your PR as an opportunity of doing it for every remaining vendor: #305.

Since it is the more general approach (and was long overdue), would you mind closing this PR in favor of #305? 🙇

[mojomex]

Thank you for your quick response!

Closed in favor of #305.
