Adding test vectors for AEGIS256 to wycheproof.

Browse Source

AEGIS256 is described here:
https://eprint.iacr.org/2013/695.pdf
https://competitions.cr.yp.to/round3/aegisv11.pdf

Test vector generation:
I'm using a python version for the generation of the test vectors:
CL 252436459
The test vectors are then compared against a second implementation:
CL 252613429

Third party test vectors:
I don't have any third party test vectors.
https://eprint.iacr.org/2013/695.pdf contains some test vectors.
But, these test vectors can only be reproduced if the number of rounds
in finalize is reduced from 7 to 6.
Both papers describe AEGIS256 with 7 rounds in finalize.
All third party implementations I've found use 7 rounds, such as
this one:
