Try to transfer the XP from the given XP orb entity into the given fluid handler. If the handler has enough room to store only part of the orb's XP, it will reduce the orb's XP by the amount taken (assuming the action is execute). Does not remove the entity; the caller should do that iff this returns true.

Parameters:

handler - the fluid handler

orb - the XP orb

action - whether or not to simulate the action

Returns:

true if the XP orb was (or could be) fully absorbed into the fluid handler
