Create a public deployment to showcase the Player

[nicolaslevy]

Similar to quic.video, it would be great to have a site where we can deploy the player to showcase its capabilities and use it as a platform to promote the project.

For this, we will also need to deploy englishm/moq-rs with the goal of having a relay and a video source.

Issue for the relay deployment: cloudflare/moq-rs#30

I might handle both of these together.
