Update README.md

SmartIR is a component for controlling AC units and TV devices via Infrared controllers. An IR controller such as Broadlink RM is required.

The key features of the component are:

* Support for Base64, Broadlink Hex and Pronto codes.

* Support for external temperature and humidity sensors (Climate platform)

* Support for external on/off sensor that monitors whether your device is actually On or Off. This may be a power monitor sensor.

* Support for voice assistants.
