Module map_reduce

The map_reduce module contains the Chain struct, which represents a map-reduce chain.

A map-reduce chain is a combination of two steps - a map step and a reduce step. The map step processes each input document and the reduce step combines the results of the map step into a single output.

The Chain struct is generic over the type of the Step and provides a convenient way to execute map-reduce operations using a provided Executor.
