feat: add QOIZ image codec

Browse Source 
Add a new QOIZ codec (UUID 229cc6dc-a860-4b52-b4d8-053a22b3892b) for
SetSurface command. The PDU data contains the same data as the QOI
codec, with zstd compression.

Some benchmarks showing interesting results (using ironrdp/perfenc)

QOI: 10s user CPU, 96.20% compression
QOIZ: 11s user CPU, 99.76% compression
