Cool command, just a few code style changes mostly.

I still like @haykam821's suggestion of extending the functionality of this command to maps you are looking at. Should I open a separate issue for that?

[wagyourtail]

he can pr that xd

[wagyourtail]

that was much harder than expected but it works

[wagyourtail]

wait, since when can I not request multiple reviews

[xpple]

Some style changes.

Is this pull request still maintained? The functionality can be extended in a later pull request to include #399 and #400.

I think that would be more suited to a more general command to get the nbt of a held item.
that wouldn't nicely format it, but it'd be more useful.

or is that not stored there anymore

[wagyourtail]

I guess since cgetdata doesnt return it for entity @s SelectedItem it doesn't.

I think I'll leave /cmap info for someone else to implement

Looks good to me.
