valign only has center and top

[LuckyForce]

When aligning vertically for rows their is either the option to do it on top or center. I need bottom for my use case.

// TODO # Experimental
            // ------------------------------------------------------------------------------
            // align vertically
            let topTextToAlignVertically = 0;
            if(valign && valign !== 'top'){
              const heightText = this.heightOfString(text, {
                width: width - (cellPadding.left + cellPadding.right),
                align: align,
              }); 
              // line height, spacing hehight, cell and text diference
              topTextToAlignVertically = rowDistance - columnSpacing + (rectCell.height - heightText) / 2;  
            }
            // ------------------------------------------------------------------------------
