Adapt compare_ds.py to compare text elements (also includes a STIG Benchmark mode)

[yuumasato]

Description:

• Improve the script so that it can compare text elements in the Rule. Elements like title, description, fixtext and warning.
• Includes a new option o compare STIG Benchmarks.

Rationale:

• We need a tool to compare STIG Benchmark releases
• We couldn't easily know what changed in a Rule, besides its remediation and checks.

The PR works great for me. It's probably a good idea to add an option to output files to a specific folder --output diff/ so it doesn't clutter the current directory.
