Add issue remarks for differential analysis and timing attacks

Created by: Zapotek

Timing attacks

Add remarks for:

• Average response time of default element submissions.
• Average response time of stabilization submissions after payload ones.
• The incremental delays used for each phase.

Or make this per phase instead of showing averages, that'll provide a clearer picture.

Differential analysis

Add remarks for:

• Control/true/false payloads used.
