drft: diff reviewer, file tree

A diff re/viewer that navigates by files, as a tree, so larger patches are no longer a pain to read.

Currently it doesn't verify the given diff but assume it's good.

$ cargo install drft
$ git diff | drft
$ drft some.patch

Without a vowel, it could be pronounced either draft or drift, but we tend to avoid the latter for patches.

Fun fact: its commits are reviewed with itself, i.e. EYOD.
