Library for sending notifications to Telegram from a device to ESP32. There is a built-in queue of outgoing messages for delayed sending (for example, when there is no Internet)

Dependencies:

• https://github.com/kotyara12/rStrings
• https://github.com/kotyara12/reLed
• https://github.com/kotyara12/reWifi

Notes:

• libraries starting with the re prefix are only suitable for ESP32 and ESP-IDF
• libraries starting with the ra prefix are only suitable for ARDUINO compatible code
• libraries starting with the r prefix can be used in both cases (in ESP-IDF and in ARDUINO)
