Decoder for BIL images.

At the moment, only single band BIL files are supported and it is tested only on IGN elevation WMS and WMTS layers.

 // Create an elevation source
const source = new WmsSource({
url: 'https://data.geopf.fr/wms-r',
projection: 'EPSG:2154',
layer: 'ELEVATION.ELEVATIONGRIDCOVERAGE.HIGHRES',
imageFormat: 'image/x-bil;bits=32',
format: new BilFormat(),
});

const elevationLayer = new ElevationLayer({ source });

map.addLayer(elevationLayer);
