 Each test is an input length and three outputs, one for each of the hash,
 keyed_hash, and derive_key modes. The input in each case is filled with a
 repeating sequence of 251 bytes: 0, 1, 2, ..., 249, 250, 0, 1, ..., and so on.
 The key used with keyed_hash is the 32-byte ASCII string "whats the Elvish word

+context", also given in the `purpose_string` field below. Outputs are encoded
 as hexadecimal. Each case is an extended output, and implementations should
 also check that the first 32 bytes match their default-length output.
