Augmented tensors repr

[Ardorax]

Change the way of representing an augmented tensor. Clearer separation between property with new separator and without unnecessary ones.

Old way:
baseline=0.5372559229941272, projection=pinhole, distortion=1.0, normalization=255, mask={2:torch.Size([2, 1, 370, 1224]),3:torch.Size([2, 1, 370, 1224]),}cam_intrinsic=torch.Size([2, 3, 4])cam_extrinsic=torch.Size([2, 4, 4])flow={flow_occ:[2, 2], flow_noc:[2, 2], }disparity={warped_disp_noc:torch.Size([2, 1, 370, 1224]),warped_disp_occ:torch.Size([2, 1, 370, 1224]),}scene_flow={'[3, 3]'},
New way:
baseline=0.5327254400790535; projection=pinhole; distortion=1.0; normalization=255 mask={1:torch.Size([2, 1, 375, 1242]), 3:torch.Size([2, 1, 375, 1242]), 6:torch.Size([2, 1, 375, 1242]), 7:torch.Size([2, 1, 375, 1242])}; cam_intrinsic=torch.Size([2, 3, 4]); cam_extrinsic=torch.Size([2, 4, 4]); flow={flow_occ:[2, 2], flow_noc:[2, 2]}; disparity={warped_disp_noc:torch.Size([2, 1, 375, 1242]), warped_disp_occ:torch.Size([2, 1, 375, 1242])}; scene_flow=[3, 3]

Should I add more linebreak to improve readability but it will take more space ?

[Data-Iab]

I believe that line breaks sorted in an ascending length would give better readability

distortion=1.0
scene_flow=[3, 3]
normalization=255
projection=pinhole
baseline=0.5327254400790535
cam_intrinsic=torch.Size([2, 3, 4])
cam_extrinsic=torch.Size([2, 4, 4])
mask={1:torch.Size([2, 1, 375, 1242])
flow={flow_occ:[2, 2], flow_noc:[2, 2]}
warped_disp_occ:torch.Size([2, 1, 375, 1242])}
disparity={warped_disp_noc:torch.Size([2, 1, 375, 1242])
