Clojurians Log v2

cool; thanks. seems like the docs are pretty shaky on that.

I believe it stops at refs by default, but accepts an option ::m/walk-refs true to also deref refs. here's the only example I can find https://github.com/metosin/malli/blob/52ea58a36ff5172b38dfc526ca638afa7226a4a0/test/malli/util_test.cljc#L834

probably a better example is the implementation of deref-recursive, except also add ::walk-refs true to the options https://github.com/metosin/malli/blob/52ea58a36ff5172b38dfc526ca638afa7226a4a0/src/malli/core.cljc#L2851-L2863
