renv::dependencies() has become slow in release 1.0.8

[HenningLorenzen-ext-bayer]

With 1.0.8, renv::dependencies() takes 15-20 seconds to run. On the same project with 1.0.7, it used to be 2-3 seconds.

Thanks for the bug report; I was able to reproduce. I'll take a look.

I've made a number of optimizations to the implementation of renv::dependencies() in 16c05d5; any chance you could give it a download and let me know how things look? You can use e.g. renv::install("rstudio/renv") to install the development version of renv for testing.

Great work! The optimized version not only beats v1.0.9 but also v1.0.7. 💪
