Is there a good very fast implementation for integer root (x^{1/n}) and ln for BigDecimal?

I wrote an ln implementation that was good enough for my needs, I'm happy to share it, or try to PR it if desired

I did this in a few hours, I'm sure it could be better but I'm still using it and it's working fine:
