[FEATURE] Remove playerdata

[forgiobombi]

The plugin will have the following commands

/btei rmpd <username> will convert the username of the player to uuid and will remove files with the name uuid.yml from world/playerdata/uuid.yml and plugins/Essentials/userdata/uuid.yml

/btei rmepd <username> will do the same process of converting the uuid and will remove the uuid.yml file only from plugins/Essentials/userdata/uuid.yml

/btei rmwpd <username> will do the same process of converting the uuid and will remove the uuid.yml file only from world/playerdata/uuid.yml

Also add a confirmation message for when a playerdata file is successfully removed and one if it wasn't possible removing the playerdata.
