[BUGFIX] Use serialized variant of setup in GifBuilder hash

If generated images used the exact X/Y coordinates all time (as in one documentation example) the initial image would always be reused.

Serializing the setup array using ConfigurationService::serialize keeps performance but includes enough data to never reuse similarly positioned mask images.
