FIx output reader

[keurfonluu]

• Fixed: standard output reader failed to be parse when data contains integer values (e.g., MATERIAL) (fixes #145).
• Fixed: some Docker related issues.

Reminders:

• [x] Run invoke format to make sure the code follows the style guide,
• [x] Add tests for new features or tests that would have caught the bug that you're fixing,
• [x] Write detailed docstrings for all functions, classes and/or methods,
• [x] If adding new functionality, unit test it and add it to the documentation.
