Implement a secret sharing-based PSI protocol to replace the FHE component in APSI.
The original APSI uses Fully Homomorphic Encryption (FHE) for polynomial evaluation, which can be computationally intensive. This PR introduces an alternative using arithmetic secret sharing with Beaver triples, which can offer performance benefits and simplify dependencies by leveraging OpenSSL instead of SEAL.
