Add support OpenSSL 1.1

Subj. Currently you can't import pyelliptic with openssl 1.1 and greater. Also pyelliptic not understand LD_LIBRARY_* env for change lookup folder.

Hi,

I don't have the time or the motivation to correct properly pyelliptic.

Moreover, this method (using ctypes) to use OpenSSL isn't stable. I'll make a last release removing the ECDH/ECDSA part but keeping Cipher and Hash stuffs and tag pyelliptic as deprecated.

I suggest to looking at pyOpenSSL, cryptography, pySodium, curve25519, etc ...

Regards.

Thanks for the answer. Ah... I should be porting some libs from PyElliptic now.

@stalkerg Definitely use https://github.com/pyca/cryptography

Wondering why the solution wasn't "update readme to make clear pyelliptic will only ever work on OpenSSL 1.0.x and tag as deprecated". My issue is that pyelliptic was the only library I could get to compile on a RaspberryPI A+/B+ properly.
