Move annotation formats to dataset manager (#1256)
* Move formats to dataset manager * Unify datataset export and anno export implementations * Add track_id to TrackedShape, export tracked shapes * Replace MOT format * Replace LabelMe format * Add new formats to dm * Add dm tests * Extend TrackedShape * Enable dm test in CI * Fix tests * Add import * Fix tests * Fix mot track ids * Fix mot format * Update attribute logic in labelme tests * Use common code in yolo * Put datumaro in path in settings * Expect labels file in MOT next to annotations file * Add MOT format description * Add import * Add labelme format description * Linter fix * Linter fix2 * Compare attributes ordered * Update docs * Update testsmain
