Ouster SDK integration

[matlabbe]

• Live LiDAR on Linux (not tested, sensor needed)
• OSF on Linux
• PCAP on Linux
• Live LiDAR on Windows (not tested, sensor needed)
• OSF on Windows
• PCAP on Windows (fails to get packets, automatically returns end of file?)
• Live LiDAR on Mac OS X (not tested, sensor needed)
• OSF on Mac OS X(not tested)
• PCAP on Mac OS X(not tested)

Install https://github.com/ouster-lidar/ouster-sdk

Verify rtabmap is detecting it at the end of cmake output:

--  LiDAR Drivers:
--   With Velodyne VLP16       = YES
--   With Ouster SDK 20231031  = YES            <------

Ouster sample data to try on: https://static.ouster.dev/sensor-docs/#sample-data

Integrated to tools:

• rtabmap-lidarMapping
• rtabmap-lidarViewer (may crash on Ubuntu 22.04 with default system PCL/VTK, known issue here)

Integrated to standalone UI:

On Windows, use OusterSDK DLL version: ouster-lidar/ouster-sdk#608 to avoid "silent crash" (in this function) with the static library (still not sure what is causing this, rtabmap includes a bunch of dependencies that may clash with the static library).

For convenience, apply this patch:

so that OusterSDK library installed in Program Files can be detected automatically with cmake, otherwise we need to do:

cmake -DOusterSDK_DIR="C:/Program Files (x86)/ouster_example/lib/cmake/OusterSDK ..

Well, if C:\Program Files (x86)\OusterSDK\bin is on the PATH, that may work even if we don't change project name (not tested).
