XP pickup

I feel like just like items i want baritone to be able to pickup xp orbs just like it does items

a simple on off for it scanning and going to xp orbs and picking them up

it would be quite nice to have this feature since often times u wanna go mining to get some xp and the bot not picking them up defeats the purpose of automatically mining for xp for servers with veinminer
