Add Native ZSTD Compression Support for ROM Archives

📋 Summary

This request is to add full, native support for ZSTD-compressed archives (.zip and .7z) in LaunchBox, particularly to improve compatibility with RetroAchievements and general ROM handling.

❗ Problem

• LaunchBox currently does not support ZSTD-compressed archives by default.

• Cheevo (RetroAchievements) scanning fails on .zip/.7z files compressed with ZSTD—even if users manually patch in ZSTD-capable versions of 7-Zip.

• In some cases, trying to scan these files causes LaunchBox to crash.

• Users must currently replace internal 7-Zip binaries to gain partial compatibility, but this is unreliable and not officially supported.

💡 Proposal

• Integrate ZSTD decompression support directly into LaunchBox.

• Ensure cheevo scanning works properly with ZSTD archives.

• Prevent crashes and fallback issues when ZSTD files are encountered.

✅ Benefits

• Fully supports modern compression formats used in No-Intro and other curated ROM sets.

• Eliminates the need for manual 7-Zip modifications.

• Ensures RetroAchievements scans are reliable across all supported formats.

• Improves ROM loading and extraction performance.
