Add Themis using the BN curve (#549) * Add THEMIS Policy Contract * Add test with 128 ads * Add instructions * Allow clients to work concurrently * pub(crate) utils to find unused code * Remove serde_json dep * Drop dependency on primitive_types * Add a simpler inner_product * Use elgamal for proof verification * Migrate to Ristretto Also, use Serde for instruction serialization * Add remaining instructions to processor * Remove rand 0.6 dependency * Add instruction constructors * Add e2e test * Move client test out of BPF build * Add BPF instruction count test Shows us that serde makes too many recursive calls and causes a very high instruction count (Vec<U256> becomes impractical). * Use Borsh serialization and test calculate_aggregate() Bump BPF instruction count limits after upgrading compiler * Test SubmitProofDecryption BPF instruction count * Remove CompressedRistretto This drops SubmitProofDecryption instructions by ~2.5M. Also, box up more RistrettoPoints, because they're huge (120 bytes) and blow up the BPF stack. * Add transaction size metrics and update BPF counts * Switch back to BN * Add benchmarking * Use configured keypair path * Make num_users configurable * Make testnet benchmark an example, not a test * Exclude themis client from CI build Because of Travis failure on itertools dependency

# Brave THEMIS
An implementation of Brave's THEMIS research project. This project contains
two privacy-oriented smart contracts, the Policy Smart Contract (PSC) and
the Fund Smart Contract (FSC). Together, the two contracts allow users to
be compensated for engaging with ad publishers. The users do not expose
their identities or preferences.
