prog: don't materialize uncompressed image in Deserialize
Currently we uncompress all images in Deserialize to check that the data is valid.
As the result deserializing all seeds we have takes ~40 seconds of real time
and ~125 seconds of CPU time. And we do this during every syz-manager start.
Don't materialize the uncompressed image.
This reduces real time to ~15 seconds and CPU time to 18 seconds (no garbage collections).
In syz-manager the benefit is even larger since garbage collections take longer (larger heap).
