`trunc_mat()` deprecated in tibble

[krlmlr]

https://github.com/tidyverse/tibble/pull/1517 breaks trunc_mat() for good, this affects tidygraph. This is important so that I can get rid of a ton of legacy code in both tibble and pillar.

I can release to CRAN, but the output in tidygraph will be slightly different. Please see https://pillar.r-lib.org/articles/extending.html for the new API. Happy to help.
