Add support for shadow-cljs

[eoliphan]

Shadow CLJS has much better support NPM, etc libraries.

Thanks for the headsup, I will look into that.

Any update on this? This is the error that's being reported by shadow-cljs currently:

The required namespace "cljsjs.antd" is not available, it was required by "antizer/core.cljs".
The namespace was provided via :foreign-libs which is not supported.  
Please refer to https://shadow-cljs.github.io/docs/UsersGuide.html#cljsjs for more information.
