Extracting prime field modulus

Hi there,
as part of our efforts to implement [ECTester](https://github.com/crocs-muni/ECTester) we are working with the Intel Crypto Primitives library. The recent deprecation and removal of some ECC functions hit hard, and I am now struggling to find a way to implement some functionality we rely on.

Concretely, assuming that I have an IppsGFpECState *curve I want to be able to extract all of its parameters (think of it like I want to serialize them/export them). I found APIs to get the **a, b, Gx, Gy, n, h** parameters via the `ippsGFpECGet` and `ippsGFpECGetSubgroup` calls. However, I am not able to extract the prime modulus in any way that does not go around API restrictions in a really hacky way. The `ippsGFpECGet` call only gets me the `IppsGFpState` and I cannot seem to be able to extract the modulus from that.
