Support Offsetting in Stack

[Templarian]

It may be useful for some people to have the ability to offset when stacking icons.

<Stack>
  <Icon x={2} y={2} path={mdiAccount}/>
</Stack>

I don't have a use for this, but we've told users to use the stack to solve combining icons in the past.

Thank you @Templarian! I will give his a try.

@oliverkx This isn't an implement feature yet. No one actually has asked for it to be implemented.

Often we try and add icons with overlays so it might be better to request the icon in the main repo.
