Get an example decoder function for a nested spec.

Given a spec, returns an example decoder function. The decoder function parses string serialized example protos into tensors according to the given spec.

example_spec list/tuple/nest of ArraySpecs describing a single example.
batched Boolean indicating if the decoder will receive batches of serialized data.
compress_image Whether to decompress image. It is assumed that any uint8 tensor of rank 3 with shape (w,h,c) is an image. If the tensor was compressed in the encoder, it needs to be decompressed.
