TerriaJS / terriajs

To reproduce

Add the following WMTS server - https://base.maps.vic.gov.au/service?service=WMTS&request=GetCapabilities&version=1.0.0
Add "Vicmap Basemap - Web Mercator - Aerial" layer
Notice that the tileMatrixSet has tileWidth and tileHeight set to 512
But, catalogItem.tileWidth and catalogItem.tileHeight are still set to the default value 256

Because of nullish coalescing (??) order here:

terriajs/lib/Models/Catalog/Ows/WebMapTileServiceCatalogItem.ts

Lines 545 to 549 in e6ec10a

    
           minimumLevel: this.minimumLevel ?? tileMatrixSet.minLevel, 
        
           maximumLevel: this.maximumLevel ?? tileMatrixSet.maxLevel, 
        
           tileWidth: this.tileWidth ?? tileMatrixSet.tileWidth, 
        
           tileHeight: 
        
             this.tileHeight ?? this.minimumLevel ?? tileMatrixSet.tileHeight,

(I think there is also a mistake where this.minimumLevel is being used to set tileHeight

	minimumLevel: this.minimumLevel ?? tileMatrixSet.minLevel,
	maximumLevel: this.maximumLevel ?? tileMatrixSet.maxLevel,
	tileWidth: this.tileWidth ?? tileMatrixSet.tileWidth,
	tileHeight:
	this.tileHeight ?? this.minimumLevel ?? tileMatrixSet.tileHeight,

WMTS tile height/width isn't pulled from Tile Matrix Set
