Defect Dojo integration

**Additional context**
Defect dojo is an aggregator repository of vulnerabilities and it would be interesting to have an integration between ThreatMapper and it.

**Describe the solution you'd like**
The main goal would be to have vulnerabilities detected by Threat mapper and injected into Defect dojo (https://owasp.org/www-project-defectdojo/) where they could be correlated with other tools.

**Describe alternatives you've considered**
Instead of an integration, a simple extraction of information from Threat mapper could be enough. It could be just a standard extraction of data in CSV or JSON.
