BIP 32: Test vectors for leading zeros

Browse Source 
These additional test vectors will ensure all future implementations are
interoperable.

RECENT CHANGES:
* (24 Feb 2017) Added test vectors for hardened derivation with leading zeros
* (16 Apr 2013) Added private derivation for i ≥ 0x80000000 (less risk of parent private key leakage)
* (30 Apr 2013) Switched from multiplication by I<sub>L</sub> to addition of I<sub>L</sub> (faster, easier implementation)
* (25 May 2013) Added test vectors

===Test vector 3===
These vectors test for the retention of leading zeros. See [bitpay/bitcore-lib#47](https://github.com/bitpay/bitcore-lib/issues/47) and [iancoleman/bip39#58](https://github.com/iancoleman/bip39/issues/58) for more information.
