Can't read in complex 2dseq

Hi, 
I'm trying to load `2dseq` files that are complex (got them from a custom reco in ParaVision), but in the end the data I get is magnitude data.
I think it one could try to test if the data 2x the expected size in the `deserialize` function of `Schema2dseq` and then perform either complex reco or just continue.
