Before, limbs were stored in little-endian. But to use Arrays.mismatch to our advantage, it is better to have it big-endian. This commit makes UInt256.java big-endian in limbs. We still need to migrate all tests and benchmark. Signed-off-by: Thomas Zamojski <thomas.zamojski@quadratic-labs.com>
Also added tests that were failing and now pass. Signed-off-by: Thomas Zamojski <thomas.zamojski@quadratic-labs.com>

Small cleaning up of the private methods for addition and compareLimbs. Should be easier for the compiler. Signed-off-by: Thomas Zamojski <thomas.zamojski@quadratic-labs.com>
UInt256 used int[] for limbs, primarily for simplicity, e.g. having the possibility to widen to long. However, methods exists to work with long[] and no widening. This commit implements long limbs. To avoid widening, we do: 1. add: overflow check 2. mul: native multiplyHigh (compiled to assembly mulq) 3. div: more complicated, see the gnump division paper.
