  - Decouple TXT Report file writing and formatting logic (1/6)

    This commit is the first of a series aiming to decouple the writing and formatting logic of text report files in the asdc tool. Unfortunately because of a significant amount of technical debt, a small hack had to be done so that the header of the file is not written twice. This will be removed in a future change.
