newRPL: new decimal library, new benchmarks

[Claudio L.]

For those following the progress of newRPL, I was able to run some quick benchmarks of transcendental functions on newRPL using the new decimal library, which is now officially part of newRPL.
You can read more about it here.

Now that the port to the new decimal library is complete (or almost), work will resume on the user interface and other areas.
