This merge request includes the following changes:
- Added the GridSample feature, which supports two interpolation modes: bilinear and nearest.
- Provided four test models: gridsample_bilinear.onnx, gridsample_nearest.onnx, gridsample_bilinear_conv.onnx, and gridsample_nearest_conv.onnx. The last two models demonstrate a common use case of GridSample, where the grid is generated by a convolutional network and transformed into the (N, H, W, 2) data format using Transpose.
- Added support for converting the GridSampel feature from float to int16.
