251 use jinja for job script rendering

[bschroeter]

Replaced in-source job script generation with Jinja templating.

For context - this simplifies the generation of job scripts (and indeed anything that interpolates into a template), meaning that we can remove the multiline string blocks, which are sensitive to whitespace, and abstract them into separate files.

This results in cleaner and more flexible code going forward and opens up opportunities to change the underlying templates at a moments notice.

A small comment about typing. Otherwise all good. I approve but it would be good to fix the typing before merging if I am correct in my comment.

[ccarouge]

Above it says load_package_data() outputs a dictionary but interpolate_string_template() takes a string as input.

I'm guessing the typing of the function's return value for load_package_data() needs to be updated to be Union[str, dict]?

[bschroeter]

yes you are correct, now that we are potentially reading raw data this is needed. I'll update that now.
