JVET-AE0048 item 1: Add missing value ranges for nnpfc_pic_width_num_minus1, nnpfc_pic_width_denom_minus1, nnpfc_pic_height_num_minus1, and nnpfc_pic_height_denom_minus1

JVET_AE0060_COND_SIG_INF: Signal nnpfc_chroma_loc_info_present_flag only when nnpfc_out_order_idc is not equal to 0 and infer nnpfc_chroma_loc_info_present_flag to be equal to 0 when not present.

Implementation of AD0056 item 5, don't signal nnpfc_input_pic_output_flag[i] flags when nnpfc_num_input_pics_minus1==0 and infer nnpfc_input_pic_output_flag[0]=1 instead
