> Support data masking built-in function '{*}mask_show_last_n{*}'
> Return a masked version of str, showing the last n characters unmasked. Upper case letters should be converted to "X", lower case letters should be converted to "x" and numbers should be converted to "n". For example, mask_show_last_n("1234-5678-8765-4321", 4) results in nnnn-nnnn-nnnn-4321.
