Adjust aerodrome zoom levels (#3879)

Change aerodrome initial & final zlevel and check waypixels

Change initial zoom level to z11 for airports, z13 for minor aerodromes, change last zoom level to <17 or waypixels<192000
After this PR, the icon for airports (with an IATA code) renders from z10 to z17 on points, and the text label from z11-17. Minor aerodromes (lacking IATA or ICAO codes) render the icon from z12-18 and text labels from z13-18. But in both cases, the icon and label are no longer shown if the area is greater than way_pixels 192000 (for example, 192 x 1000 pixels)
