Investigate Adobe DSP about fluentui-token-pipeline

[TravisSpomer]

After looking into this further, I don't really see any interesting opportunities for alignment. DSP is just another JSON-based output format for tokens. If it happens to catch on as a popular format, it wouldn't be too difficult to build a DSP from the token pipeline, but as it stands, I don't see any value in doing that right now. I'm also not sure how we'd represent more complex things like gradients in their schema, since structured data (JSON objects) appears to be unsupported. (A string containing JSON would work. Or just a CSS linear-gradient string, but then anything that isn't CSS that wanted to consume it would then have to parse a CSS function..)
