[Feat] Margin support when using positionOptions

[phantrungdien]

I use React Native CLI, I want the text to be positioned at the top right, 60px from the top, and 60px from the right, but it's not working.

Please add the following settings to positionOptions to support X and Y axes:

For example:

const STAMP_TOP_OFFSET = 60;
const STAMP_RIGHT_OFFSET = 60;

positionOptions: {
          position: Position.topRight,
          X: STAMP_RIGHT_OFFSET,
          Y: STAMP_TOP_OFFSET,
        }

react-native: 0.84.0
react-native-image-marker: 1.2.11
