This speeds up the asset writer significantly:
For the 3D sample bag:

So ~10%. For pipelines that do less this can be even 30% or more.
- Refactor ProbabilityGridPointsProcessor for code reuse.
- Adds Image::width and height.
- Adds GetFilename for FileWriter.
Related to googlecartographer/cartographer_ros#475.
* Adds DeleteScanMatcher() to 3D constraint builder
* Add possibility to remove submaps and scans from the 3D optimization
problem.
* Implements TrimmingHandle in SPA.
Before, the relative change in pose due to odometry in the
2D pose graph optimization problem was incorrectly done in
the tracking frame. Instead, the gravity aligned frame in
which the 2D poses are stored must be used.
Fixes#515.

This PR introduces a new option that specifies the number of seconds
after which global matcher searches are performed if no recent global
constraints have been found between the submap's and the node's
trajectory.
This changes submap_visualization.proto that multiple textures can be provided.
As of now, the first texture is generated from the high resolution
grid, which is the same as before.
The second texture is generated from the low resolution grid.
Updating the connectivity needs the data of nodes for which
constraints were added, so we postpone trimming to after the
connectivity update.
Also makes sure the mutex is held as necessary.
This PR fixes a crash when cartographer is run in localization mode due
to the map trajectory not having been properly added to the
ConnectedComponents.
* Introduce TrajectoryConnectivityState.
This class will be used to track the connectivity state (including the
last connection time) between pairs of trajectories.
