This library houses extra operators that are not part of the official RxPHP library.

• cut - splits a stream with a delimiter
• repeatDelay - repeats an observable sequence with when it completes after a delay

    $observable->repeatDelay($initialDelay, $maxRetries, $maxRetryDelay, $retryDelayGrowth);

• retryDelay - retries an observable sequence when it errors after a delay

    $observable->retryDelay($initialDelay, $maxRetries, $maxRetryDelay, $retryDelayGrowth);

• FromEventEmitterObservable - converts event emitters like react streams to RxPHP Observables
