Oasis buffs Commercial Hub, Aqueduct, City Park, Huey Teocalli and Etemenanki

Oasis is already at a disadvantage because they can only be found in the desert. They don't do anything special other than give Food and Gold. So I buffed them. Features: 1. Oasis gives major adjacency bonus (+2 Gold) to Commercial Hub and Suguba - Like rivers, Oasis are trading hubs in the desert. 2. Aqueduct and Bath get +1 Amenity if adjacent to an Oasis. - Oasis is like Geothermal Fissure; hot and wet. 3. City Park get +1 Amenity if adjacent to an Oasis. - Currently, City Parks get an amenity when adjacent to Coasts, Lakes and River. Why not Oasis? 4. Oasis get +1 Food and +1 Production from Huey Teocalli wonder. - Oasis is like a small lake in the desert. 5. Oasis get +2 Science and +1 Production from Etemenanki wonder. - Oasis is like Marsh in the desert.
