Amazon Dash Button to MQTT Bridge

Sends an MQTT message when an Amazon Dash button press is detected.

Dash Button Setup

Go through the normal Dash button setup in the Amazon app, but when asked to select a product, simply exit out of the setup process.
Find the mac address of the Amazon button. This can usually be achieved through your router. If in doubt, use a MAC address vendor checker to make sure the MAC is reigstered to "Amazon Technologies inc."
(Optional) Block the button from accessing the internet. Different routers have different ways of achieving this, but typically a simple IPTables rule will achieve this.

Install Python (>= 2.7), as well as scapy, configparser and paho-mqtt from pip.
