v0.8.1

The default settings have been updated. Now, only the main output file is saved by default, while the log and diagnostic files are disabled. Users can adjust these settings in the configuration file.

After:

settings = {
    # ...
    "SAVE_DIAGNOSTIC": False,
    "SAVE_LOG": False,
    "SAVE_OUTPUT": True,
    # ...
}

Before:

settings = {
    # ...
    "SAVE_DIAGNOSTIC": True,
    "SAVE_LOG": True,
    "SAVE_OUTPUT": True,
    # ...
}

This change focuses on the main output file, as the log and diagnostic files are helpful but not essential for cash flow modelling. By simplifying the default settings, the basic process becomes tidier.
