Add wrapper.rs providing ZGFX segment framing utilities for both uncompressed and compressed data: - wrap_uncompressed(): Wraps raw data in ZGFX segment format - wrap_compressed(): Wraps ZGFX-compressed data with COMPRESSED flag Supports both single segments (≤65535 bytes) and multipart segments for larger data. Fully compliant with MS-RDPEGFX specification. This enables server implementations to send EGFX PDUs without compression while maintaining protocol compliance. Refs: Devolutions#1067

Adds ZGFX segment wrapping utilities for encoding data in RDP8 format.
Summary
wrap_uncompressed(): Wraps raw data in ZGFX segment structure without compressionwrap_compressed(): Wraps pre-compressed data with the COMPRESSED flag setSupports both single segments (up to 65535 bytes) and multipart segments for larger payloads per MS-RDPEGFX section 2.2.5.3.
Use Case
Enables server implementations to send EGFX PDUs in spec-compliant ZGFX format. This is the wrapping layer; compression support will follow in a separate PR.
