* Upgrade JNI interface * Input signatures can be DER or compact format, output signatures are always in compact format * Input public keys can be compressed or uncompressed, output public keys are always uncompressed * Name and parameters match libsecp256k1's * JNI implementation is now straightforward No more ByteBuffers Exceptions are thrown in case of failures * Update src/nativeMain/kotlin/fr/acinq/secp256k1/Secp256k1Native.kt * Add public key compression method Co-authored-by: Salomon BRYS <salomon.brys@gmail.com>
