/**
 * Checks if a value is an instance of a class or a class name. Useful when you want to check if a
 * value is an instance of a class that may not be defined in the current scope. For example, if you
 * want to check if a value is an `OffscreenCanvas` instance, you might not want to do the song and
 * dance of using `typeof OffscreenCanvas !== 'undefined'` and then shimming `OffscreenCanvas` if
 * the types aren't around.
 *
 * @example
 *   if (isInstanceOf(value, 'OffscreenCanvas')) {
 *     // value is an OffscreenCanvas
 *   }
 *
 * @param value The value to recursively check
 * @param class_ A string or class that the value should be an instance of
