Replace the implementation of maths in `UnsignedBigInteger` and `SignedBigInteger` with LibTomMath. This gives benefits in terms of less code to maintain, correctness and speed. These changes also remove now-unsued methods and improve the error propagation for functions allocating lots of memory. Additionally, the new implementation is always trimmed and won't have dangling zeros when exporting it.
