The `build` subcommand can now take in any number of recipe files and
will build them all in parallel. Along with this new ability, I've added
a way to easily distinguish which part of the build log belongs to which
recipe. Check out the `docker_build` action of this PR for an example.
## Tasks

consistent
- [x] Update color ranges based on @xynydev 's feedback
- [x] Deal with ANSI control characters in log output
