   @HyukjinKwon can we add support for jsons where value has null:
   
   Example: json <- '{"firstName":"Bob", "lastName":null}' 
   
   I am thinking that schema_of_json function can take an argument which casts all null as string ?
   
   `def schema_of_json(json: Column, cast_null_as_string : Option[Boolean] ) = new SchemaOfJson(json.expr, cast_null_as_string.getOrElse(false))
   `
