Describe the enhancement

Allow home assistant to manage airplay speaker groups using the existing pyatv Output Device commands to add/remove additional airplay receivers for an aTV/Homepod.

Use cases

There's no good way to automate which airplay receivers are in the group for an aTV/HomePod (in any ecosystem). Similar but inferior solutions:

• HA media player grouping doesn't work with Apple native functionality like Siri commands and iOS adjustments.
• Apple Home has limited automation with gaps like selection of the leader device, volume setting isn't programmatic, and group changes can only be triggered by playing media.
• Manually creating them on iOS/macOS is tedious and inaccurate.

Examples:

• When the aTV is playing and presence is detected on the deck, add the outdoor speakers to the aTV's airplay group.
• When arriving home on weekdays add kitchen, living room, and dining room airplay speakers to den aTV speaker group and play chill music.

Anything else?

A reasonable limitation would be to only add/remove other devices using the AppleTV integration.

Hey @scpotter, I have missed to raise a feature request, but have been working on a PR for the the past few days for this: home-assistant/core#163367

It can group players via the UI and actions in scripts/automation.
Grouping via Siri or apple devices will be reflected too.
