.FastAIStatefulEncoding

			abstract type StatefulEncoding <: Encoding

Encoding that needs to compute some state from the whole sample, even if it only transforms some of the blocks. This could be random state for stochastic augmentations that needs to be the same for every block that is encoded.

The state is created by calling encodestate(encoding, context, blocks, sample) and passed to recursive calls with the keyword argument state. As a result, you need to implement encode, decode, encode!, decode! with a keyword argument state that defaults to the above call.

Same goes for decode, which should accept a state keyword argument defaulting to decodestate(encoding, context, blocks, sample)
