Description

Is your feature request related to a problem? Please describe. zlib and deflate are old and slow. Zstd is a faster and modern almost drop-in replacement.

Describe the solution you'd like Adding a new encoding type that is a copy paste of ZRLE, but using Zstd instead of zlib.

Contributor guide

Research direction
Examine the existing ZRLE encoding implementation in TigerVNC and replace the zlib compression with Zstd, following the same structure. Test performance and correctness.
