Feature

What is the current behavior?
useContext triggers update if the whole passed store changed

What is the expected behavior?
add keys argument to trigger update only if specified keys in passed store changed

It would be useful to improve application speed.

F.e.

function MyComponent() {
  // example context value
  // I want to ignore age changes (who does't hehe)
  // {
  //   name: 'Max',
  //   age: 35
  // }
  // dep's-like style
  const {name} = useContext(MyContext, 'name')
  // or
  // comparator style 
  const {name} = useContext(MyContext, (current, old) => current.name !== old.name)
}
