[Cryptech Core] Accelerating asymmetric core development

Aloha!

Since we now have a working EIM interface and integration moves forward
I've started to focus more on what we need for the Alpha board.

In terms of use case functionality what really is missing are the
asymmetric primitives: modexp for up to 8192 bit operands for RSA, P-256
and P-384 EC and then Curve25519.

For RSA what is needed is a really godd bit exact functional model that
can be used to test iterative operations with possible internal data
types. The model is then used to drive the HW implementation with good
intermediate test vectors.

In order to get this model done asap, I've considered bringing in a
colleague of mine - Peter Magnusson. Peter has a good background in
mathematics and embedded SW development. Peter is also good at crypto
and knows the domain. (He has for example implemented all attacks like
Lucky13, Beast in order to study them.)

My suggestion is that Peter would assist me locally to develop the
model. I would still be the one that checks and commits code into the
repo. The amount of time (hours) developing the cores would be the same,
it would just happen faster to allow us to reach working cores sooner.

Does this sound ok with the rest of core?
