tfjs models are working

[Jonathhhan]

I converted your onnx models to tf saved model and with the current tfjs converter to tfjs models and it works very well. here is my code (based a lot on yours):

This is how I converted the models:
tensorflowjs_converter --input_format tf_saved_model clip-text-vit-32-tf clip-text-vit-f16-tfjs --quantize_float16
tensorflowjs_converter --input_format tf_saved_model clip-image-vit-32-tf clip-image-vit-uint8-tfjs --quantize_uint8
