[Statistic.Countdown] Would be nice to have a pause/start api.

[EggTronic]

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

In some cases, countdown might need to be paused and continue later on.

What does the proposed API look like?

const { Countdown } = Statistic;
const deadline = 1000 * 30; // mili seconds, not depend on Data.now()
const ref= useRef(null);
const autoStart = false; // boolean

// once mounted, we can call following API to control the countdown
ref.start()
ref.pause()

Countdown: ref={ref} autoStart={autoStart} value={deadline} onFinish={onFinish}

The lib called 'react-compound-timer' may give you some idea.

is pause functionality added in Statistic.Coundown?

context: Object
refs: Object
updater: Object
syncTimer: ƒ () {}
startTimer: ƒ () {}
stopTimer: ƒ () {}
formatCountdown: ƒ () {}
valueRender: ƒ () {}
_reactInternals: FiberNode
_reactInternalInstance: Object
state: null
countdownId: undefined
isReactComponent: Object
setState: ƒ () {}
forceUpdate: ƒ () {}

How can we pause the time? stop and start timer api is available but pause api is not available.
