fix: Resolve frameSrc not found warning

[mattcompiles]

Resolves #164

[maraisr]

Wait... I get it! So this "frameSrc" is something I can export from my frame component housed file? @mattcompiles

[mattcompiles]

That's correct.

[maraisr]

Do you think you can help me with a list of things that are undocumented with Playroom, so I can help you guys out in writing some. cc @mattcompiles @michaeltaranto @markdalgleish

[michaeltaranto]

This is currently a feature we are proving out, so it's deliberately undocumented at this point. We are hoping to get to building a site soon, but was there something else on your list?

[maraisr]

Generally speaking new features that are being tested get released under an @next tag, rather than the stable. Perhaps playroom could do something similar?

And re the list, I was hoping you could provide one.

[michaeltaranto]

Worth remembering that Playroom is pre-1.0, so everything is a next tag.

We document the features that we are happy for users to start consuming. If consumers are digging into the code and using internal apis, that's fine as they are explicitly opting in to an unstable api.

[maraisr]

Oh right... Did not know that that 0.x.x means beta. My bad!

[maraisr]

Pretty funny hey.

[maraisr]

... I'm serious.
