* Adding large numbers
* The sodium_add() function accepts two pointers to unsigned numbers encoded in little-
* endian format, a and b , both of size len bytes.
* It computes (a + b) mod 2^(8*len) in constant time for a given length, and overwrites a
* with the result.
* This function was introduced in libsodium 1.0.7.
