Retroachievement support in Lemuroid

[Funvita456]

Is your feature request related to a problem? Please describe:
I feel that Lemuroid is missing something without RetroAchievements support. This feature adds motivation and a sense of accomplishment while playing retro games, and it would be great to have it integrated.

Describe the solution you'd like:
I would love to see Lemuroid support RetroAchievements, allowing users to link their accounts, track progress, and unlock achievements for compatible games. It would make playing on Lemuroid even more enjoyable and rewarding.

Describe alternatives you've considered:
I’ve thought about using other emulators that already support RetroAchievements, but switching between apps is inconvenient. Lemuroid is already my go-to emulator, and having this feature would make it a complete solution for retro gaming.

Additional context:
RetroAchievements (https://retroachievements.org/) is a free service that provides achievements for classic games across various platforms. Adding support for this would make Lemuroid stand out even more among other emulators. Thank you for considering this request!
