Allow lakelines at native sizes (#1475)

This PR reduces the minimum lake line zoom to z3, allowing the largest lakes to show a renderable label. The lakeline function is restricted by the LineLabel() function, which limits lakelines to only those that are big enough to render a text label.  Therefore, further restricting lakelines by zoom is not necessary.
