Add TruckDrive dataset support

[stepankonev]

TruckDrive (Torc Robotics / Princeton, CVPR 2026) is a long-range highway heavy-truck dataset. Add a first-class source-dataset processor + converter covering cameras, the ego trajectory, the Aeva FMCW LiDAR, and ego-frame 3D detections.

• src_datasets/truckdrive/: processor, converter, IO (extracted devkit layout, gt_trajectory parsing, sync-id cross-sensor matching, float64x11 Aeva xyz decode) and calibration geometry (TF-tree BFS, pose assembly).
• enums.py: map each rig camera to the canonical CameraDirection that matches its facing (FRONT, FRONT_LEFT, SIDE_LEFT, REAR_LEFT, ...) so keys stay consistent across datasets, and add members only for the four genuinely-extra views the eight canonical slots cannot name -- the forward telephoto pair (FRONT_{LEFT,RIGHT}NARROW) and the rear-facing side pair (SIDE{LEFT,RIGHT}_BACK). Additive, non-breaking.
• Detections are emitted in the ego (velodyne) frame with the ego vehicle's own cab/trailer and DontCare groups excluded; the class taxonomy is vendored from the paper's supplementary Table 2.
• configs/truckdrive.yaml, scripts/extract_truckdrive.sh and prepare_dataset_truckdrive.sh, unit + env-gated real-frame tests, and a README support-table row.

Radar, accumulated-depth, short-range Ouster LiDAR and lane lines have no StandardE2E target yet and are not ingested.
