[Suggestion] Better metas management

[NoltoxGit]

Hello,
At the moment, DeluxeMenus data is sorely lacking in clarity and comprehensibility. That's why I'm making this suggestion!

Would it be possible to add the ability to manage and display a player's metas with DeluxeMenus using commands such as :

• /dm meta (Player) <set/remove/add/subtract> <key> <type> <value> → Edit meta to a player
• /dm meta (Player) list → Show all metas of a player
• /dm meta (Player) show <meta> → Show a specific meta of a player

Why ?

Because I use several metas in my menus, and when I need to check the value of a player if it has such and such a value, it would be much more practical if we could edit them and display different information about them.
