First completed round trip test of sFUL/FUSD -> FULM

After all of the trials and tribulations, we finally have a viable prototype!

The code is working for conversions of all kinds. There are a number of
strange and annoying bugs still present, like the rings in the CLI wallet are
misbehaving at times. But we have a viable product.
