add "Detect from image"

[fumitakayano]

Thank you for making this Extension.
The camera and bone system give AI art a new sense of certainty.

Could you implement additional functions to make this function even easier to use?

"Detect from image" would be very useful to have a function to estimate the pose taken by the character in the loaded background image.

Since the functions are only pseudo-inferences, we think that the pose does not need to be accurate in the world space as long as it can infer the state seen from the current camera.

I am sorry that not able to implement this feature. This project just runs on the browser and doesn't have the power to detect poses. If possible, I will try to do it in the webui extension (https://github.com/nonnonstop/sd-webui-3d-open-pose-editor)

@fumitakayano Already supported "Detect from image", enjoy it.
