3. Fix the borrow logic in subtraction so it works for > 128 bits.
4. Rewrite fromString to use a simpler but correct algorithm and also to
not set the bit width contrary to the user's request.
5. Optimize toString a bit by making it only do one Knuth divide per
iteration instead of two.
With these changes, all arithmetic passes (verified by pari/GP) up to
1024 bits except for certain division cases.
