Any SignedAmount can now be cast to Amount since the range it the same.
Specifically, the range for SignedAmount is (- 21 million, 21 million)
while the range for Amount is (0, 21 million).  Therefore any value from
Amount can be cast to a SignedAmount and it will work.  Note it's not
the same and still requires checking when going from SignedAmount to
Amount since Amount can't handle the negative range.
