This work might look like extensive for just fixing a small issue like
the include rendering, but it will all be heavily reused by the
skywater-pdk scripts that will be released soon.
This commit;
- Adds Makefile for creating a self contained conda environment under
`env/conda`
- Installs required Python dependencies into the environment (which is
currently just the `rst_include` tool).
- Has a Makefile to generate `README.rst` from `README.src.rst`
- Has Travis CI run on repository and check that the `README.rst` file
has been rebuilt and committed if any of the dependencies have
change.
