OL.Layer.WMS(name (String), url (String), params (Object), options (Object, optional) )
params (Object): This object contains key-value pairs of parameters to send to the WMS service. Common parameters include:
* LAYERS: Specifies the names of the layers you want to request from the WMS service.
* TRANSPARENT: Usually set to "true" to request transparent images that can be overlaid on other layers.
* FORMAT: The image format for the tiles, commonly "image/png" for transparency.
* VERSION: The version of the WMS request protocol, such as "1.1.1" or "1.3.0".
* STYLES: Defines styles to apply to layers, often an empty string if default styles are desired.
options (Object, optional): This optional object provides additional configuration options for the layer. Common options include:
* opacity: Sets the opacity of the layer, typically between 0 (fully transparent) and 1 (fully opaque).
* isBaseLayer: Boolean value indicating whether this layer is a base layer.
* projection: Defines the spatial reference system for the layer.
* tileSize: Specifies the size of the tile as an OL.Size object.
* attribution: Provides attribution text for the layer, often displayed on the map to give credit to data providers.
