Check if there if there is another bubble open

What does this PR do?

• contains a new method called isBubbleOpen

Why this PR?

My previous experience with the existing methods worked fine until I decided to launch the bubble in the useEffect. This ended up spawning multiple bubbles on launch. I tried the hideFloatingBubble method but it only closed the recent bubble opened and not the others. So I introduced this method that checks for an open before opening a new one.

How can this be manually tested?

import {
  showFloatingBubble,
  isBubbleOpen,
} from "react-native-floating-bubble";

async function showBubble() {
    try {
      const _isBubbleOpen = await isBubbleOpen();

      if (!_isBubbleOpen) {
        await showFloatingBubble();
      }
    } catch (error) {
      console.log(error);
    }
}
