Record the hashes of all available binaries in the lock file

[eitsupi]

Right now, the lockfile only records the binary for the platform it was generated on.
This isn't ideal, as it means the lockfile won't work across different platforms.

Looking at how tools like https://github.com/aquaproj/aqua handle this, we'll probably need to rethink the structure of both the lockfile itself and the metadata published by the package registry.

This would be nice, since I'm currently having to figure out how top produce a dbc.lock in my macOS laptop, which can also be used in a Linux-based Docker image.

EDIT: in the meantime using the official docker image does the trick

docker run --rm \
  --platform linux/amd64 \
  -v $PWD:/work -w /work \
  columnar/dbc:latest \
  sync
