Feat/cancel image

[DaveyEke]

This PR adds an isActive prop that cancels an image request if false and let's it go through if true

Example Usage:

import { useIsFocused } from '@react-navigation/native'

  function MyScreen() {
    const isFocused = useIsFocused()

    return (
      <NitroImage
        image={{ url }}
        isActive={isFocused}
        style={styles.image}
        resizeMode="cover"
      />
    )
  }
