Rebuild the structure

Overhaul

This package should be rebuilt from scratch around the mantle asynchronous framework. This would allow to work on each actor as if it were synchronous, thus creating a simple architecture.

Actor interface

interface Actor
{
    public function __invoke(Receive $receive): Receive;
}

Receive::message(T)|Receive::signal(Signal)
    ->on(T::class, callable(T, Address(sender)): void)
    ->onChildFailure(callable(Address(child)): void)
    ->onPostStop(callable(): void)
    ->onPreRestart(callable(): void)
    ->onTerminated(callable(Address(child)): void)
    ->stopWhen(callable(): bool);

This style allows for a more declarative approach and may help optimize the system by not calling the callables when declared.

Instead of using Receive::stopWhen() maybe the continuation pattern should be used on each callable passed to Receive
