Tasker Support

Many Android apps include support for [Tasker](https://tasker.joaoapps.com/), a phone automation app which supports third-party plugins, allowing events on the phone to trigger actions in the app.

This seems like a natural fit for the Home Assistant companion app. It would allow Tasker users to call services, render templates, and get entity states directly within Tasker automations. The classic example is being able to mute/pause media players when receiving a phone call.

I currently maintain the standalone [Home Assistant Plug-In for Tasker](https://github.com/MarkAdamson/home-assistant-plugin-for-tasker), but I would love to merge the functionality with the official Home Assistant app, allowing me to reduce the number of Home Assistant apps I have on my phone.
