Fix pep517 build (#182)

* Fix PEP 517 build by adding cffi to build requirements

Add cffi>=1.17.1 to pyproject.toml build-system requirements to prevent
pip from falling back to legacy build mode. This ensures CFFI is available
in the isolated build environment that PEP 517 uses.

* Remove deprecated setup_requires to enforce PEP 517 builds

Remove setup_requires from setup.py since build requirements are now
properly declared in pyproject.toml. This eliminates the deprecated
fetch_build_eggs code path and forces proper PEP 517 build behavior.
