A fiber-based supervisor utility for evaluating effects across an impure boundary. This is
useful when working with reactive interfaces that produce potentially many values (as opposed
to one), and for each value, some effect in F must be performed (like inserting each value
into a queue).
Dispatcher is a kind of Supervisor and accordingly follows the same scoping and
lifecycle rules with respect to submitted effects.
Performance note: all clients of a single Dispatcher instance will contend with each
other when submitting effects. However, Dispatcher instances are cheap to create and have
minimal overhead, so they can be allocated on-demand if necessary.
Notably, Dispatcher replaces Effect and ConcurrentEffect from Cats Effect 2 while only
requiring an cats.effect.kernel.Async constraint.
Submits an effect to be executed, returning a Future that holds the result of its
evaluation, along with a cancelation token that can be used to cancel the original effect.
