Tools to convert ONNX files (NCHW) to TensorFlow format (NHWC)

Add, Div, Mul, Sub

• https://github.com/PINTO0309/onnx2tf/releases/download/1.1.28/sinet_320_op.onnx Shrink a tensor whose input_tensor_1 and input_tensor_2 have the same rank and all but one dimension is 1. This is a workaround to avoid the pattern of failure of explicit_broadcast in subsequent processing. https://github.com/gmalivenko/onnx2keras/issues/84

  e.g.
  input:
    input_tensor_1: [1,80,80,12]
    input_tensor_2: [1,12,1,1]
  
  output:
    input_tensor_1: [1,80,80,12]
    input_tensor_2: [12]
