rHttpUtils2 - Http Client with synchronous requests queue [module]
Extended Erel''s module with 8-level FIFO queue manager. Allows to schedule the HTTP-requests one by one, not ideal, with big RAM memory consumption, but works with ESP32. It allows to add requests into a queue and the manager will run them automatically storing against non-stable Internet-connection.
