Increase brightness and generate unique MQTT client ID

Release 2.0.2 brings the following new features and improvements for ANAVI Light Controller:

• Generate unique MQTT client ID based on the machine ID.
• Increase brightness by setting PWM range 0 to 255. According to the documentation the default range in Arduino core for ESP8266 is up to 1023: https://arduino-esp8266.readthedocs.io/en/latest/reference.html#analog-output

Thanks to @hackman for suggesting both improvements!

Change the default MQTT broker

Release 2.0.1 brings the following new features and improvements for ANAVI Light Controller:

• Change the default MQTT broker to mqtt.eclipse.org: https://mqtt.eclipse.org/
• Update Arduino library WiFiManager to 0.15.0
• Publish state as JSON payload to avoid errors in Home Assistant, fix by @jonathanmtran

Home Assistant discovery and other improvements

Release 2.0.0 brings the following new features and improvements for ANAVI Light Controller:

• Support Home Assistant automatic discovery over MQTT
• Turn on LED D1 on ANAVI Light Controller if the device is not connected to local WiFi network and needs initial configuration
• Wait for a few seconds while LED D1 is blinking immediately after turning on ANAVI Light Controller to allow reset by keeping SW1 pressed
• Append the last 5 characters of the machine ID to the WiFi Access Point (AP) to simplify the identification of the ANAVI Light Controller during the initial setup
• Support MQTT messages with large payload for reporting back the current state of the RGB LED strips on topic stat/dev-id/color
• Add DEBUG macros, disabled by default, if enabled additional debug information will be printed in the serial monitor
