Pairless

Converts the Apache Milagro Crypto Library (amcl) to a submodule to reflect the latest changes.

Additionally it uses a new pairing feature which reduces the number of Miller loops that need to be done speeding up verification.

Dependency update

Updates all external dependencies

Little endian domain

Interpret the signature domain bytes as little-endian, for compatibility with the Ethereum Foundation's implementation.

Fast verify

• Adds optimization for single signature verification
• Adds a fast verify multiple method.

SHA256

Changes hashing algorithm to SHA256 (from Keccak).
