BREAKING RELEASE: Add MQTT API, RESTCLIENT is now IO_HTTP

BREAKING Change

• RESTClient is now IO_HTTP to conform with IO_MQTT naming. Examples have been changed to reflect this change.

Changes:

• Examples folder has been split into mqtt and http to organize examples.

• a MQTT Class, IO_MQTT has been added to adafruitio for accessing the Adafruit IO MQTT API with a CircuitPython Adafruit IO client.

  • Examples of using this class can be found here: https://github.com/adafruit/Adafruit_CircuitPython_AdafruitIO/tree/master/examples/mqtt

To use in CircuitPython, simply install the Adafruit CircuitPython bundle.

Updated examples

Examples updated to run on boards with built-in AirLift ESP32 Co-Processors (such as the PyPortal or Metro M4 WiFi Lite) without editing the example code.

New Time API and Updated Examples

This release adds Adafruit IO CircuitPython support for the new Adafruit IO Time API.

• Calling receive_time returns localized time to the CircuitPython RESTClient, based on the device's IP address, as a struct_time](https://circuitpython.readthedocs.io/en/3.x/shared-bindings/time/__init__.html#time.struct_time) #19

• Note: The previous /time endpoint returned a plaintext response, instead of json. This release removes plaintext-handling from the library.

• Updated all examples to match the Adafruit IO naming scheme in the PyPortal's secrets.py file.

Adding User-Agent and Header Handling

• Append a User-Agent (Adafruit-IO CircuitPython specific) for this library onto existing request headers for the server to identify CircuitPython clients.
• Added a new _create_headers method for HTTP requests to reflect correct header encoding in the Adafruit ESP32SPI dependency (https://github.com/adafruit/Adafruit_CircuitPython_ESP32SPI/releases/tag/1.3.4).
