Logical bug of `self.img_embed`

[hubert0527]

The persistent attribute self.img_embed is assigned to the current image latent here:

GeoWizard/geowizard/models/geowizard_pipeline.py

Lines 248 to 249 in 0a60193

	if self.img_embed is None:
	self.__encode_img_embed(input_rgb)

It is understandable to save AE computation, but the variable is not reset after the depth/normal ensemble. Thus, making a second call to the pipeline inference will result in the wrong input condition.

A simple (but not so clean) fix is to assign self.img_embed=None before return:

GeoWizard/geowizard/models/geowizard_pipeline.py

Lines 199 to 201 in 0a60193

	normal_colored_img = Image.fromarray(normal_colored)
	return DepthNormalPipelineOutput(

Thanks, we have fixed it.
