Update requirejs config

Ahh, now it all makes sense. Is there a recommended way to support shimmed modules?

In particular, I want to support Vega-Embed, which is a shimmed library that depends on Vega and Vega-Lite to be loaded already. I don’t see any way in d3-require to define the dependency chain.

Hello forum! Require is related but didn’ help me with this particular issue. I don’t want to pre-build the package because always want to use the latest Vega and Vega-Lite versions.

Thank you for your help Tom!
