This commit introduces two new files: `BENCHMARK_RESULTS.md` and `benchmark_results.txt`, which document the performance metrics of various cryptographic operations, including ECDSA signing, verification, and ECDH key exchange. The results provide insights into operation times, memory allocations, and comparisons with C implementations. Additionally, new test files for ECDSA and ECDH functionalities have been added, ensuring comprehensive coverage and validation of the implemented algorithms. This enhances the overall robustness and performance understanding of the secp256k1 implementation.
