Veinmining doesn't require actual amount of food

[VanyaBaou]

Veinmining is only checking for "food isn't 0" when doing an operation This means people can have 0 food and 0 saturation and do this:

• Eat 1 beetroot, to not be starving
• Veinmine 64 blocks, hunger goes to 0
• Repeat

Yep, the issue here is that Ultimine adds exhaustion and then checks the player's food level. But the food level isn't updated until the next tick. So we need to compare current exhaustion vs. current food+saturation, and stop mining if exhaustion is high enough that it would cause the player to reach food level 0.
