Moves the pblock by the specified offset in units of the pblock range type.
For example, if the pblock is SLICE_X0Y0:SLICE_X2Y2 with an offset of (0,2),
the result would be SLICE_X0Y2:SLICE_X2Y4. However, if the pblock range
is using clock regions, the offset unit would be two clock regions away.
xOffset - Offset of the pblock range type in the X (column) direction
yOffset - Offset of the pblock range type in the Y (row) direction
True if the move was successful, false otherwise;
