SiriKit Media Intents integration (ask Siri "Play <song> on <my app>") [PLEASE REMOVE ME]

[nickshoe]

Feature proposal

Add SiriKit Media Intents support to let users ask Siri to "play song on my app".

Motivating use case(s)

It would be awesome if this plugin included Siri integration for controlling media playback, like it already does for Google Assistant.

I've developed a Flutter plugin to support voice interactions on iOS (ask Siri "play on "), by implementing SiriKit Media Intents.
I didn't have time to consider a PR for integrating this feature in this plugin, but IMO it would be very reasonable to do so since audio_service already provides Google Assistant support. I could work on this and I'm willing to share the plugin code for those who want to work on this.

And, by the way, audio_service plugin is amazing and it saved me a lot of time and headaches while developing my app. So, thanks to the auhtor and all the contributors. Kudos.

Sorry for the inconvenience, I've experienced serious problems using GitHub while creating this issue and the duplicated issue seems to be a side-effect.
