This discards the pose correction logic used that was for the D455 not for
an euroc dataset. It will be reintroduced in a later commit with an
appropriate device.
- Implement xrt_slam_source instead of xrt_fs
- Merge intermediate sink pointers into xrt_slam_sinks in_sinks
- Add out_sinks for downstream passage of data
- Make speed playback option a double (float was not precise enough)
- Add use_source_ts playback option to optionally use original dataset timestamps
- Fix colored datasets not working
A squash of the following commits.
d/euroc: Add Euroc driver initial boilerplate
d/euroc: Implement xrt_frame_node interface
d/euroc: Implement mainloop thread start flow
d/euroc: Parse samples from data.csv files
d/euroc: Determine dataset information at start
Also use that information to provide a xrt_fs mode and to know if
right camera images are available to use.
d/euroc: Produce frames for left and right sinks
d/euroc: Implement xrt_imu_sink
d/euroc: Implement playback properties
d/euroc: Implement pausing with UI state machine
d/euroc: Show IMU and progress data in UI
d/euroc: Make sure to give in nullptr or valid pointers to wrapL8
d/euroc: Unreference frames when done with them
d/euroc: Fix leaks with debug sinks, and work around free issue
d/euroc: Refactor playback to produce samples with current timestamps
d/euroc: Fix double free by separating debug sinks from downstream sinks
