Benjamin Gaignard 5ae05bb42a codecparsers: Defering computation of pps and sps fields 
While possible defer computataion of pps and sps fields until
slice parsing since it may happens that bitstreams don't encoded
them in expected order.
A example weird ordered bitstreams is VPSSPSPPS_A_MainConcept_1
conformance test.
