Namespace handling

[abaeyens-imod]

Issue description

Specifying a namespace when launching the Septentrio node does not effect the names of the published topic - they are always published in the root name space.

For topics like /insnavgeod this is not much of an issue, it's clear they're from the Septentrio and there aren't other nodes that publish such topics, but for others like /imu and /pose this will cause confusion. Also, preferably nodes ought to operate in a given namespace when they are launched in that given namespace.

Steps to reproduce the issue

1. Setup Septentrio hard & software
2. Specify which namespace to launch the Septentrio nodes with in the Septentrio launch file
3. Launch with that launch file
4. Look at the names of the published topics

What's the expected result?

arne@laptop:~$ ros2 topic list
/<namespace>/insnavgeod
/<namespace>/imu
/<namespace>/pose
etc.

What's the actual result?

arne@laptop:~$ ros2 topic list
/insnavgeod
/imu
/pose
etc.

Additional details

This is likely due to the topics being defined with a preceding slash in septentrio_gnss_driver/src/septentrio_gnss_driver/communication/message_handler.cpp, e.g.

publish<INSNavCartMsg>("/insnavcart", last_insnavcart_);

instead of

publish<INSNavCartMsg>("insnavcart", last_insnavcart_);

Version

Compiled septentro_gnss_driver from source, branch ros2, HEAD commit 207c37bc.
