Reporting enchancements

[carl-baillargeon]

Add the following functionalities to reporting:

• Markdown report #740
• CSV report #672
• Word document
• Add a knob to also save the full command result output
• Add test timestamps + report timestamp

As discussed internally, for now we will implement the following in ANTA CLI for CSV and MD reports:

• anta nrfu csv and anta nrfu md-report
• Both commands will have their own options/flags (e.g. anta nrfu md-report -o ./anta_md_report.md
• Both commands will show a Summary on the screen, and the full report (all results) will be saved in a file
