Add compression and decompression support for k256 (secp256k1) keys. #5

This is a proposed change to for using OpenSSL to rapidly decompress compressed k256 keys. I have two qualms about what I have done:

  1. I've taken a module named ecc_compact and made it serve two purposes compaction and compression.
  2. In order to expose the dual nature, I've renamed some of the public functions and types. This will require changes to the primary dependent on this library: libp2p_crypto.
