Network management improvements, KeepAlive

Improvements for KeepAlive

• keep_alive is now an init kwarg
• The loop method now checks the time and sends a PINGREQ (expecting a PINGRESP, this is handled in the ping() method) to the server if the time elapsed is greater than or equal to the provided keep_alive value.

Network Management Improvements
*loop_forever now calls loop instead of _wait_for_msg. Also now handles network control, for both the socket and the NetworkManager (currently only the WiFiManager) objects.

• Properties for network management (is_wifi_connected, is_sock_connected) have been added as well as additional management for both the socket and ESP32SPI wifi module (reconnect_socket, reconnect_wifi)

Fix CONNECT for long password/username/client identifiers

This release fixes connect() for use with large (>127 bytes) payloads such as a long password (JSON Web Tokens), client identifier, or last-will message.

• The remaining length calculation previously used by this library has been removed in favor of using the algorithm described by the MQTT V3.1.1 specification (https://docs.oasis-open.org/mqtt/mqtt/v3.1.1/os/mqtt-v3.1.1-os.html#_Toc398718030).
• Default keepalive value increased to 60 seconds to ensure the MQTT broker rejects incorrect connections, instead of hanging.

Initial Release!

Initial release of MiniMQTT, a MQTT Client Library for CircuitPython.

This library aims to be independent of network hardware. However, at this time the MiniMQTT library is only available for CircuitPython devices connected over WiFi.

This library is based off previous work performed by pfalcon on uMQTT (and the umqtt port to ESP32SPI by beachbc). MiniMQTT's primary difference from uMQTT is it uses calling conventions and method names similar to The Eclipse Foundation's Paho.Mqtt.Python.

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

To use in CPython, pip install adafruit-circuitpython-minimqtt.
