Generate an installable Python package for a pipeline. Includes binary data,
meta and required installation files. A new directory will be created in the
specified output directory, and the data will be copied over. If
--create-meta is set and a meta.json already exists in the output directory,
the existing values will be used as the defaults in the command-line prompt.
After packaging, "python -m build --sdist" is run in the package directory,
which will create a .tar.gz archive that can be installed via "pip install".
If additional code files are provided (e.g. Python files containing custom
registered functions like pipeline components), they are copied into the
package and imported in the __init__.py.
