Description

loo has been running for four hours now on seven cores. I have no idea when it will finish, so intermittent progress reports would be great (e.g., every 10%). Specifically, I'm using brms::LOO(brmsfit) which I believe calls loo in the background.

Contributor guide

Research direction
Look for the main computation loop in the loo package, typically in the loo function or related. Identify where iterations are performed and insert a progress bar or callback that reports progress at 10% increments. Consider using R's built in txtProgressBar or the progress package for nicer output.
