[Feature-Request]: Enhance Persistence with Database Storage

[Ash-2k3]

Description:

Currently, the script uses a text file (processed_chains.txt) to store the hashes of processed certificate chains. While this works for small datasets, it might become a bottleneck as the number of chains increases.

Proposed Solution:

Investigate and implement a database-based persistence mechanism to store processed chains. This will offer several benefits:

Improved Scalability: Handle larger datasets with ease.
Enhanced Data Integrity: Ensure data consistency and prevent corruption.
Query Flexibility: Enable efficient searching and filtering of processed chains.
Better Organization: Provide a structured way to manage chain data.
