Vincent Ambo 29bab159ab feat(depot-build): Add a tool to build at arbitrary tree locations
Assuming you're in `/depot/fun/clbot`, you can do this:

    tazjin@frog /d/f/clbot (master)> depot-build
    Building //fun/clbot
    /nix/store/i1zc6g58wa4819kyhaqi12zsh3hr31ph-clbot

It is automatically added to the $PATH using direnv, too.
