// ConvertMapI2MapS walks the given dynamic object recursively, and
// converts maps with interface{} key type to maps with string key type.
// This function comes handy if you want to marshal a dynamic object into
// JSON where maps with interface{} key type are not allowed.
//
// Recursion is implemented into values of the following types:
// -map[interface{}]interface{}
// -map[string]interface{}
// -[]interface{}
//
// When converting map[interface{}]interface{} to map[string]interface{},
// fmt.Sprint() with default formatting is used to convert the key to a string key.
