identity — 2D `misc` op

• Data kinds: any → any

• Call: fullseye.apply(img, "identity", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

• HALCON equivalent: copy_image (the HALCON reference is a useful guide to its meaning and parameters)

Usage

Identity mapping. Mapped to HALCON's `copy_image (Copy an image and allocate new memory for it.), but unlike copy_image`, which allocates new memory and duplicates the image, this implementation simply returns the input array as-is (it does not duplicate it).

`a, b は未使用。sort が ANY`（image/region/feature いずれの入力にも一致）なのはこの op だけの特別扱いで、パイプラインの型を変えずに「何もしない」スロットを置くために使う（進化がスロット数を埋めたいだけのとき等）。値を作り直さず入力をそのまま返すため、呼び出し側で戻り値を書き換えると入力の配列も一緒に変わる点に注意。
