Local source code feature (using bundle images)

Reference shipwright-io/build#717

Add `bundle` package that contains convenience code to push a local
source code directory as a bundle image to a container registry.

Add new flags for container image and local directory settings.

Add `github.com/google/go-containerregistry`.

Add `github.com/schollz/progressbar/v3`.
