Adafruit-circuitpython-minimqtt

This release adds:
* `add_topic_callback` method: Registers a callback_method for a specific MQTT topic.
* `remove_topic_callback` method: Removes a registered callback method
* [Usage example](https://github.com/adafruit/Adafruit_CircuitPython_MiniMQTT/blob/master/examples/minimqtt_pub_sub_blocking_topic_callbacks.py)

To use in CircuitPython, simply install the [Adafruit CircuitPython bundle](https://circuitpython.org/libraries).

To use in CPython, `pip3 install adafruit-circuitpython-minimqtt`.

Read the [docs](http://circuitpython.readthedocs.io/projects/minimqtt/en/latest/) for info on how to use it.

This release adds:
* **BREAKING**: `last_will` method renamed to `will_set` to mirror Paho-MQTT.
* `message` kwarg changed to `payload`
* LWT properties set in init instead of directly calling `will_set`
* https://github.com/adafruit/Adafruit_CircuitPython_MiniMQTT/pull/36 Updates to the `will_set` method to correctly set payload data as bytes.

This release:

* Patches broker hostname issue (https://github.com/adafruit/Adafruit_CircuitPython_MiniMQTT/issues/25) requiring broker URL starting with HTTP/HTTPS. Drops dependency for URL prefix.
* Removed `try/except` block which improperly handles IP address strings
* Removed module's `TCP_Mode`/`TLS_Mode` constants in favor of using the interface's `TCP_Mode` or `TLS_MODE`.
* Updated examples to reflect above updates
* Updated `_cellular` and `_ethernet` examples to use MQTT, unencrypted (port `1883`) broker ports.
