add STL 3D model support

[Mon-ius]

Since V4 supports adding .STL file in examples path which can render correctly in the box. There is no need to limit ".stl" file in the accepted upload list.

Example code:

import numpy as np
import gradio as gr
import trimesh, os

def load_mesh(mesh_file_name):
    return mesh_file_name

print(
    os.path.join(os.path.dirname(os.path.dirname(__file__)), "dataset/1/output_0.stl")
)

T3D = gr.Interface(
    fn=load_mesh,
    inputs=gr.Model3D(label="3D Mesh File"),
    outputs=gr.Model3D(clear_color=[0.0, 0.0, 0.0, 0.0], label="3D Model"),
    examples=[
        [os.path.join(os.path.dirname(os.path.dirname(__file__)), "dataset/1/output_0.stl")],
        [os.path.join(os.path.dirname(os.path.dirname(__file__)), "dataset/2/output_0.stl")],
        [os.path.join(os.path.dirname(os.path.dirname(__file__)), "dataset/3/output_0.stl")],
    ],
    cache_examples=True,
)

Adding STL support can contribute a lot to 3D print industry, without extra convert, people can play more seamless 🤗

Thanks @Mon-ius ! I think this looks good to me! Tagging @dawoodkhan82 @hannahblair for quick review from them.

[Mon-ius]

Great! Some checks need external auth for vercel deploy failed, should not be a problem!

[dawoodkhan82]

Nice! tested, and works. It would be great, if you can update the model3D demo to include a .stl example.

[Mon-ius]

@dawoodkhan82 No problem! I will update a new model3D demo with .STL format file 🤗

[freddyaboulton]

Thanks @Mon-ius ! I added the stl file to the existing model3D demo as opposed to creating a new one. Will merge once CI passes!

@freddyaboulton Good Job! Cheers!
