Addresses #69

not ready to merge yet as i had set the command to specifically run to ons_python but need to generalise to all module names with jinja

Thanks for the PR.

1. This is the wrong file; you need to add this to https://github.com/ONSdigital/ons-python-template/blob/main/project_template/Makefile.jinja (templates makefile, not this repo's root template)

2. You also need to make it agnostic to the package manager, so it should be:

{{ package_manager }} run python {{ module_name }}

3. Please add this new __main__.py file to https://github.com/ONSdigital/ons-python-template#structure

This would currently raise lint failures.
