[PATCH v1] dts: add package mode config and updated README

[Dean Marx <dmarx@iol.unh.edu>]

In the current DTS setup description, the user installs poetry
with the --no-root option. However, adding 'package-mode = false'
to the pyproject.toml sets the same configuration, and running
poetry install --no-root will become an error in a future
poetry version.
