Testing aditional mcginty/snow test vectors results in a failure

[quapka]

The Rust version of Noise protocol snow contains additional test vectors. I've pulled them in and simply loaded as the other test vector files (the new ones are one layer deeper in the JSON file behind "vectors" key, I've saved the list directly).

Previously, there were 104 and now there are 408. pytest gave me 304 failures. This suggests some general problem, but the things I've checked so far (e.g. the structure of the test vectors, their keys etc.) look similar between the old snow test vectors and the new ones.

I'm going to take a deeper look.

An attempt to analyze the errors a bit more:
