Choice of secp256k1 interface

[ofek]

Hello there! I'm a maintainer of coincurve, a provider of libsecp256k1.

As of v21.0.0 there are zero runtime dependencies and we started to maintain benchmarks against other libraries. I didn't have time to add your ctypes-based code although I would love if you could share the results of benchmarks that you might have done recently.

I think we would be a good fit for this project because we frequently update to upstream releases ¹ and we provide precompiled wheels which would make installation much easier ², although I am relatively unfamiliar with your target audience.

Please let me know if you are interested in switching to coincurve for performance reasons or to free up the maintenance you have to do, or both! Definitely let me know if there is something you require which I have not yet implemented.
