• This issue will require implementation of Schnorr signature scheme in wallet-core/trezor-crypto/src/ first, similar to how wallet-core/trezor-crypto/src/ecdsa.c works.
  Reference implementation: https://github.com/Zilliqa/Zilliqa/blob/master/src/libCrypto/Schnorr.cpp
  (To port the above implementation, we will have to use trezor rand generator library instead of openssl)

• This issue will also require the implementation of the Trust wallet wrapper for Schnorr signature scheme using the trezor-crypto library. sign and getPublicKey methods must be implemented.
  Reference implementation for ECDSA with secp256k1:
  https://github.com/TrustWallet/wallet-core/blob/master/src/PrivateKey.cpp#L25
  https://github.com/TrustWallet/wallet-core/blob/master/src/PrivateKey.cpp#L50
