-// RunSimplestOT is a utility function used _only_ during various tests.
-// essentially, it encapsulates the entire process of running a base OT, so that other tests can use it / bootstrap themselves.
-// it handles the creation of the base OT sender and receiver, as well as orchestrates the rounds on them;
-// it returns their outsputs, so that others can use them.
