represents a net in which net is applied n times to the input.
[net,n] accepts a single input array s0 and produces an output array sn, computed by applying net repeatedly to si-1 to compute si .
In NetNestOperator[net,n], net should take exactly one input and produce exactly one output. The input and output must be of the same dimensions.
If net contains trainable parameters, the same parameters are used for every application of net to the input.
If net has no trainable parameters, NetNestOperator[net,n] is equivalent to a NetChain containing n copies of net.
