ros_listener: replace ofstream with file ptr, added min max dist flags for points
Better always_all_points state that will not make ImGui unresponsive. Color manager fix: Do not reset minmax when color_type panel is open.
Imshow: Now replicates show behaviour exactly. Bug fixed: Only reduced points were drawn when leaving All Points mode into no checkbox marked state.
Imshow fix: State where neither All Pts nor Always Reduce was selected did not display the very last scan index.
condense takes first scan as reference, not middle
Trajectory length skip size parameter added
ros listener looks up frame_id by itself, --skip_points added for faster bagfile re-use
ImGui color value input fixed
