LayerNorm2d

Applies Layer Normalization over a mini-batch of 2D inputs. See: `LayerNorm`

norm = nn.LayerNorm2d(3)
t = Tensor.rand(2, 3, 4, 4) * 2 + 1
console.log(t.mean().item(), t.std().item())

t = norm(t)
console.log(t.mean().item(), t.std().item())

class LayerNorm2d extends LayerNorm {

override function call (x: Tensor): Tensor
