Issue on intra_subpartitions_split_flag

[abe.kiyo]

In 7.4.11.5 Coding unit semantics, there is the description about ISP implicit split when cbHeight or cbWidth is greater than MaxTbSizeY. However the maximum CU size of ISP was limited to MaxTbSizeY x MaxTbSizeY by the adoption of JVET-N0308. So, the description should be removed as follows (this processing has already been removed in VTM);

intra_subpartitions_split_flag[ x0 ][ y0 ] specifies whether the intra subpartitions split type is horizontal or vertical. When intra_subpartitions_split_flag[ x0 ][ y0 ] is not present, it is inferred as follows:
– If cbHeight is greater than MaxTbSizeY, intra_subpartitions_split_flag[ x0 ][ y0 ] is inferred to be equal to 0.
– Otherwise (cbWidth is greater than MaxTbSizeY), intra_subpartitions_split_flag[ x0 ][ y0 ] is inferred to be equal to 1.

Good catch, thanks!

This will be fixed in the first version of D10.
