Fix: Inference of sign data hiding flags in SPS
Fix SDH flag initialization in SPS according to Brian Heng's comment: "The sps_sign_data_hiding_enabled_flag needs to be initialized to 'false' when sps_dep_quant_enabled_flag is equal to 1 here. Otherwise, the value will be uninitialized memory when used later during Picture Header parsing."
