Reset achievements unlocked via SAM after specific date

What does this change do?
This feature allows you to reset all achievements earned after a specified date.

Why is this change necessary?
I realized that years ago, I started playing very strange games just to farm achievements. As I tend to be a bit obsessive, I eventually cheated achievements in all games where it was possible. This allowed me to only play games I genuinely enjoyed.

Yesterday, my perspective changed. I no longer care about this situation and only want to track my authentic achievement data. However, I was cursed. Every time I bought a new game, I immediately went and unlocked all its achievements (for every game after March 27, 2022, according to my achievement history).

This is why I developed this feature. You can now remove all achievements earned after the date you specify.

Note: This reset is not a one-click process for all games. You still need to go into each game individually, which helps prevent accidental irreversible actions.

⚠️ IMPORTANT
After you have completed the reset process:

• Select a random game.
• Unlock one achievement.
• Then, lock it again.
  This step ensures the data on the Steam side is also properly updated.
