Issue with STIX object generation as tactic dictionary missing entries

[himynamesdave]

Have been trying to run the current code;

git clone https://github.com/DISARMFoundation/DISARM-STIX2
cd DISARM-STIX2
python3 -m venv DISARM-STIX2
source DISARM-STIX2/bin/activate
pip3 install -r requirements.txt
curl https://raw.githubusercontent.com/DISARMFoundation/DISARMframeworks/main/DISARM_MASTER_DATA/DISARM_FRAMEWORKS_MASTER.xlsx > DISARM_FRAMEWORKS_MASTER.xlsx
python3 main.py

However gives;

Traceback (most recent call last):

The error is thrown here: https://github.com/DISARMFoundation/DISARM-STIX2/blob/main/objects/tactic.py#L18

And is because tactics are hardcoded here: https://github.com/DISARMFoundation/DISARM-STIX2/blob/main/objects/tactic.py#L6

See maximise-exposure is not included.

I suspect the development of the XLSX has advanced ahead of the code, looking at the last commit date.

The addition of maximise-exposure as follows, solves the issue.

valid_tactics = ["plan-strategy", "plan-objectives", "microtarget", "develop-content",
                 "select-channels-and-affordances", "conduct-pump-priming", "deliver-content",
                 "drive-offline-activity", "persist-in-the-information-environment", "assess-effectiveness",
                 "target-audience-analysis", "develop-narratives", "establish-social-assets", "establish-legitimacy",
                 "maximize-exposure", "drive-online-harms", "maximise-exposure"]
