Onnx Squeeze to accept a list of axes

[mtobin-tdab]

Feature description

https://onnx.ai/onnx/operators/onnx__Squeeze.html
The Squeeze operation to accept a list of axes to squeeze.

Feature motivation

This is an option in ONNX which currently fails when converting:

  DEBUG onnx_ir::from_onnx: checking node squeeze1 for constants    
  DEBUG onnx_ir::from_onnx: checking input Argument { name: "const_axes__420", ty: Tensor(TensorType { elem_type: Int64, dim: 1, shape: Some([2]) }), value: Some(Int64s([2, 3])), passed: false } for const    
  ERROR burn_import::logger: PANIC => panicked at crates/onnx-ir/src/dim_inference.rs:463:9:
  Squeeze must specify only 1 axis, found 2
