Is your feature request related to a problem? Please describe

It does not appear that garnet supports bitmap compression at the moment, but some highly efficient strategies exist that are loved by developers.

Describe the solution you'd like

One such strategy is RoaringBitmaps https://vikramoberoi.com/posts/a-primer-on-roaring-bitmaps-what-they-are-and-how-they-work/

Describe alternatives you've considered

研究方向
The issue requests adding bitmap compression, specifically RoaringBitmaps, to Garnet. First, review Garnet's existing bitmap commands (e.g., SETBIT, GETBIT, BITOP) and understand the storage format. Then, explore the RoaringBitmap library for C# (e.g., https://github.com/RoaringBitmap/RoaringBitmap). The implementation would involve integrating the library to encode bitmap values, potentially at the serialization/deserialization layer. Test with existing Redis clients that expect compatible behavior. No linked PRs or assignees indicate this is unclaimed.
