fi: change decimal number behavior

93d3c67df accidentally changes number handling for finnish.

D_FRACTION2 seems to match finnish number standards. It causes the
decimals to be read as numbers instead of individual digits: 12,12 is
read "twelve point twelve" instead of "twelve point one two".

It is undocumented so it might cause regressions as well.
