Make grab head at skin stealer

Hi,
I think it would be cool at the skin stealer to have the option to get the player‘s head.
You could have two options:
1. As a give command like
```
/give @p minecraft:player_head{display:{Name:"{\"text\":\"Fast Villager\"}"},SkullOwner:{Id:"0586b057-b1bb-4cab-8ac8-e13a6c47f077",Properties:{textures:[{Value:"eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvNzBiMmRjNDRlY2U2YTliYTZkMzMxZTY0ZGI3Y2U3YTQyY2Q1NDhkZDdmZDZkZWRmODQ4YmFmZmM4MWE3NTYxOCJ9fX0="}]}}} 1
```

2. Get the value (for programmers) like
```
eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvNzBiMmRjNDRlY2U2YTliYTZkMzMxZTY0ZGI3Y2U3YTQyY2Q1NDhkZDdmZDZkZWRmODQ4YmFmZmM4MWE3NTYxOCJ9fX0=
```

I feel like this would be a cool addition.
