Bug description

Although the head tracker struct is already openend in ivas_init_decoder_front() the orientation tracking type is only set in ivas_init_decoder() leading to having the head rotation in the very first frame always being processed with HEAD_ORIENT_TRK_NONE instead of the really chosen orientation tracking type (in IVAS_DEC_Feed_HeadTrackData()). Imho the setting of the type also should be moved to ivas_init_decoder_front().

Ways to reproduce
