Very simplistic tool to aid with updating our nixpkgs channel pins:
This tool prints the correct two `*Hashes` sets to stdout, so you can
easily delete the appropriate lines in `third_party/nixpkgs/default.nix`,
run
./bin/depot-nixpkgs-update | wl-copy
and paste it into your editor.
Doing this fully automatically would be possible, but would either
a) require changing `default.nix`, so it is regex-able more easily,
b) touching something like rnix-parser which I have no motivation to
at the moment or
c) searching for the old hashes and replacing them with the new
ones. This may be a simple and worthwhile improvement in the future.
