[Feature] Subscribe function

[miniben-90]

Feature subscribe to any change of active window

Thread will be started and check every 100ms if window value has changed and call a function with information of current window.

• subscribeActiveWindow: Create a subscription with a callback function
• unsubscribeActiveWindow: Remove a specific subscription
• unsubscribeAllActiveWindow: Remove all threads

Example

import { subscribeActiveWindow, unsubscribeActiveWindow, unsubscribeAllActiveWindow } from '@miniben90/x-win';

const a = subscribeActiveWindow(activeWindow => {
  console.log('test a', activeWindow);
});

const b = subscribeActiveWindow(activeWindow => {
  console.log('test b', activeWindow);
});

const c = subscribeActiveWindow(activeWindow => {
  console.log('test c', activeWindow);
});

setTimeout(() => unsubscribeActiveWindow(c), 5000);

setTimeout(() => unsubscribeAllActiveWindow(), 10000);

Work in progress...
