RSA very slow, takes 11ms in release

[Snowiiii]

Hello, I noticed that RSA key generation takes a long time, Like the README says release build do reduce the time, But 11ms for a 1024 Key is still a lot. I would love if there where some efforts going on to reduce generation time

When #394 lands we will switch to crypto-primes for key generation.

I would expect that to be faster but haven't benchmarked myself yet.

maybe related: #29 (cannot say much otherwise, only remembered that old issue i also ran into that time :)

The current crypto-primes branch has a rough slow down of 2x last time I benchmarked, see the PR for a description of why
