The default FromPrimitive implementation for BigDecimal::from_u128 and BigDecimal::from_i128 goes through u64 and i64 respectively, rendering the default implementation useless as any number greater than 64 bits won't be parseable into a 128 bit number. The default implementation currently used can be found here:

I have overridden the default implementation so that this function actually works as intended.
