SE(3)-LIO: odometry for rough ground

IMU propagation on SE(3) and uncertainty-aware motion compensation, so jerky motion no longer breaks the odometry.

Paper: ATE 5.10 / 15.86 / 2.29 m vs. 14.07 / 17.08 / 2.50 m for FAST-LIO2

Fusion with satellite-image fixes

A per-fix confidence and a weighted solve, so fixes that jump by tens of meters carry little weight.
