Consider excluding clojurescript globally

[SevereOverfl0w]

Competing versions of guava/clojurescript (clojurescript -> google-closure-compiler -> guava) can cause clojurescript compilation errors when yada is used in the same project.

I rain lein deps with pedantic enabled, and it suggested to exclude google guava, but google guava is always coming from clojurescript, and it might be better to exclude clojurescript from yada outright.
