julia_setup() takes a lot of time #175

I'd like to use Julia in .Rmd files but the initialization is too slow. julia_setup() takes 44 seconds on my machine. Is that normal?

Julia version 1.6.3 at location /usr/bin will be used.

Does knit again also take a long time? The first time to use JuliaCall or use JuliaCall with a new version of julia will incur a long setup time. But the second time would be better. And the startup time should be improved with a newer version of julia. Generally, I would expect <20 seconds of startup time.
