[IR] Support safetensors in tensor adapters

[justinchuby]

Load safetensors as numpy arrays. It is actually incredibly easy and we are able to reuse the ir.Tensor implementation because the numpy array loaded by safetensors is memory mapped. We can use it as a normal numpy array without memory constraints.

TODO

• Add tests
• Verify bfloat16/fp8 support
