Rewrites:
- more thrown exceptions
- more debug logging (currently messing up phpunit output)
- more type-hints for primitive variables added
- writeAtPosition() must be used instead of writeData() as the later one
  increments the counter
- debug log files could contain non-text data, so let's treat them as as text
  anyway ...
