Restructure specification directory in GitHub repository

[AsamDiegoSanchez]

Describe the bug
The directory structure of the OpenMATERIAL GitHub repository doesn´t follow the given guidelines in Editorial Guide (see ASM-83)

Expected behavior
The directory structure of a repository of an ASAM specification always follows the same pattern.
The 'content' folder in the repository contains the core files for the specification.
Each main section has a separate folder which contains the file with the content of the main section and optional files with the content of the subsections.

Is it possible to adapt it now?

The structure of OSI (the only other ASAM project on Github) has been used as template, which is why it does not conform to the editorial guidelines. It is possible to adapt the structure accordingly but it would be quite time-consuming as all files had to be moved and links needed to be adapted etc. Therefore, I suggest to postpone this task until February when all content is added.
