2019-08-05libavcodec/iff: Use unsigned to avoid undefined behaviourAndreas Rheinhardt
The initialization of the uint32_t plane32_lut matrix uses left shifts of the form 1 << plane; plane can be as big as 31 which means that this is undefined behaviour as 1 will be simply an int. So make it unsigned to avoid this.
