Downgrade decimal version before decompose interface

Any version after ericlagergren/decimal#124
causes problems when saving Decimal to sql drivers like postgres. While
the best solution may be to update all the sql drivers, it has been 3
years since then, so it is better to make sure the latest version does
not have that commit. This version is the latest before it.
