safetensor streaming in from_single_file_loading()

[AbhinavJangra29]

can we add support for streaming safetensors while loading using from_single_file.
source:https://github.com/run-ai/runai-model-streamer

example:

from runai_model_streamer import SafetensorsStreamer

file_path = "/path/to/file.safetensors"

with SafetensorsStreamer() as streamer:
    streamer.stream_file(file_path)
    for name, tensor in streamer.get_tensors():
        tensor.to('CUDA:0')
