Idea: Validate Certificate Transparency Logs

# 🚀 Feature Proposal

Verify Certificate Transparency Logging on a given website

## Motivation

Compliance with agency security directives

## Example

Boolean yes/no check on whether Certificate Transparency Logs are in two places

## Pitch

My agency relies on this tool for compliance checks of public-facing websites

Start by reviewing how pshtt currently scans a given website and clarify which Certificate Transparency sources count as the required two places. Define the boolean result and expected behavior for missing or conflicting log data. Done means the tool can report a clear yes/no compliance check for a public-facing website.
