Changed for Core AI, in export_birefnet.py:
- torchvision's deform_conv2d is computed from gathers and matrix products
(identical result: max |alpha difference| 4.6e-6 in float32 on the CPU).
- The ImageNet normalisation and the final sigmoid are inside the graph; only
the last, full-size prediction is returned.
- Weights and arithmetic are float16; the input and output stay float32.
The trained weights are otherwise the authors', unmodified.
