Metadata documents with multiple schemas

[bbowyersmyth]

Porting some code from Simple.OData.Client and can't find how to retrieve types that are not in the first schema.

		var baseUrl = "https://services.odata.org/V4/Northwind/Northwind.svc";

		using var client = new ODataClient(new ODataClientOptions
		{ 
			BaseUrl = baseUrl
		});

		var metadata = await client.GetMetadataAsync(cancellationToken: CancellationToken);

		// None found
		var products1 = metadata.EntitySets.FirstOrDefault(et => et.Name == "Products");
		var products2 = metadata.EntityTypes.FirstOrDefault(et => et.Name == "Products");
