[ROS2][refact] Synchronize with master

Goal

Update feat/ROS2 branch w.r.t master branch so that the content of the slam_lib is exactly the same.

Changes

• Minor style issue in slam_lib
• Fix variable type: unsigned int NbLaserRings, int nbLasers
• Fix several errors
• Add missing display of IMU information when slam launch
• Update documentation

Checklist

• Camel case everywhere except for ROS variables/parameters
• Lower case for local variables and lambda functions
• Upper case for pour members, methods and tool functions (in Utils)
• Precise namespace when calling a function (or this->X or classe.X)
• Align code (for multiline if and while, "&&" or "||" go in upper line to ensure alignement)
• Space between if, while, for and parenthesis
• Space between operators and variables: e.g. a + b
• Space after ","
• Mind your commit titles/desc (plurals, he/she + "s", correct tags, title should begin by a verb...)
• Function names should start with a verb, variable names should start with a name
• Macros should be between {}
• Do not use negative boolean (i.e. noJoe)
• Check minimal size of the types (double -> float -> int -> uint)
• Check const and ref in functions arguments
• References should be written "type& name", not "type &name"
• Update documentation if needed
• Add MR labels [ROS]/[ROS2]/[PV]
• If ros/ros2, update task table here
• Add a comment over each non trivial function in header files
• Adda header to each new file
