Commits on Sep 15, 2020

  1. Implement equal_const_time/2 as nif 

    - add C implementation for equal_const_binary/2 (delegates to CRYPTO_memcmp)

- modify crypto.erl to delegate to nif implementation when arguments
   are binaries, otherwise go with the existing implementation for lists.

- add minimal tests.
