Results of OMMO dataset are not reproduced

[cmh1027]

1. Basically, the code can't deal with OMMO dataset because cameras in the OMMO dataset are RADIAL cameras.
2. Even though I modify the dataset_readers.py code to accept the radial cameras like below,

        if intr.model=="SIMPLE_PINHOLE" or intr.model=="SIMPLE_RADIAL":
            focal_length_x = intr.params[0]
            FovY = focal2fov(focal_length_x, height)
            FovX = focal2fov(focal_length_x, width)
        elif intr.model=="PINHOLE" or intr.model=="OPENCV" or intr.model=="RADIAL":
            focal_length_x = intr.params[0]
            focal_length_y = intr.params[1]
            FovY = focal2fov(focal_length_y, height)
            FovX = focal2fov(focal_length_x, width)

the result is much lower. For example your paper states that metrics of "13" scene is 31.60 / 0.92 / 0.22, my result is 27.81 / 0.86 / 0.22
