Description
loo_subsample() can sometimes be over-complex. srs_diff_est() is a non-exported internal function used by loo_subsample. srs_diff_est() implements difference estimator Equations 7-9 of Magnusson et al., 2020. It would be useful to export this function and provide user targeted function with documentation.

Research direction
Start by reading the internal srs_diff_est() function and its use in loo_subsample(), then compare its implementation with Equations 7–9 in Magnusson et al. (2020). Done means the function is exported and has user-targeted documentation explaining its use.
