Allow users to choose lamp exp reward for X Marks the Spot and Client of Kourend

It seems to destroy some lamps too, i'm not sure again if that's runelite bugging on my lamp settings or your script.

This is intentional behavior (and the common "meta" for irons). It destroys the lamps from X Marks the Spot and Client of Kourend to allow you to reclaim them after you've unlocked the herblore skill.

I could potentially offer the same option in the quest configuration and destroy the lamp(s) if the selected option(s) aren't available. This would be a a fairly low priority for me unless I'm missing something though.
