* \brief EC implementation "i15" for P-256.
*
* This implementation uses specialised code for curve secp256r1 (also
* known as NIST P-256), with Karatsuba decomposition, and fast modular
* reduction thanks to the field modulus special format. Only 32-bit
* multiplications are used (with 32-bit results, not 64-bit).
