Use a real template enginge (e.g. liquid) instead of home grown .create.template Files

[hf-kklein]

Our homegrown, edifact format specific .create.template files (example) are:

• not automatically checked yet (and they do have some errors)
• not parsable except by the edilibrary here

If we used a real template engine (e.g. Jinja), we could make use of all the tooling and ecosystem around it and e.g.

• write edifact automation in any langauge
• have builtin compile time consistency and syntax checks

Idea is to use liquid because it has the broadest tooling available and allows for evolution instead of revolution.
