Gree climate extension

Gree climate extension adds swing position control to the built-in Gree integration in Home Assistant. It adds select entities for each Gree climate device, one for horizontal swing and one for vertical swing. Changing the selected value sets a different swing state on the unit. A service is also available, so swing changes can be triggered from a dashboard button with a target such as an entity, a device or an area. It works locally and is set up in the UI after being added through the Marketplace.
