Function scan

scan<A, V, R>(
scanner: (acc: A) => (value: V) => Tuple.Tuple<A, R>,
): (init: A) => <K>(m: Map<K, V>) => Tuple.Tuple<A, Map<K, R>>
Scans over the Map with scanner function, a stateful computation.
Type Parameters
- A
- V
- R
Parameters
- scanner: (acc: A) => (value: V) => Tuple.Tuple<A, R>
  Function to process output R from value with accumulating state A.
Returns (init: A) => <K>(m: Map<K, V>) => Tuple.Tuple<A, Map<K, R>>
The last accumulating state and new scanned Map.
