Mismatch of ALF classification between VTM and spec

Description

In spec, (8-1261):
dirS[ x ][ y ] = ( hvd1 > 2 * hvd0 ) ? 1 : ( ( hvd1 * 2 > 9 * hvd0 ) ? 2 : 0 )

while in the function deriveClassificationBlk of VTM:

int directionStrength = 0;
if (hvd1 > 2 * hvd0)
{

directionStrength = 1;

}
if (hvd1 * 2 > 9 * hvd0)
{

directionStrength = 2;

}

Suggest to align spec to VTM for (8-1261) as
dirS[ x ][ y ] = ( hvd1 * 2 > 9 * hvd0 ) ? 2 : ( ( hvd1 > 2*hvd0 ) ? 1 : 0 )
