Converts an object representing a set of name/value pairs into a query string,
with names and values encoded properly for use in a URL. Values that are arrays
will produce multiple values with the same name.
- queryToObject // str will be: // 'key1=some%20value&key2=a%2Fb&key3=x&key3=y'
Example:
const str = Cesium.objectToQuery({
key1 : 'some value',
key2 : 'a/b',
key3 : ['x', 'y']
});
