Enable GZIP compression for API server

- Added CROW_ENABLE_COMPRESSION flag in CMakeLists.txt
- Updated api_server.cpp to use GZIP compression with Crow framework
- Modified api_server.hpp to include compression headers and define compression macro

This change improves API response efficiency by enabling GZIP compression for network communication.
