Release v2.2.5: include Eigen headers in sdist

- Add graft necpp_src/src/eigen to both MANIFEST.in files
- Use recursive-include for necpp_src/src to ensure all .h/.cpp/.h.in
  files are included in source distributions
- Fixes 'fatal error: Eigen/Dense: No such file or directory'
  when pip installing from sdist

+  - Use `recursive-include` to ensure all .h/.cpp/.h.in files are in sdist
+  - Fixes `fatal error: Eigen/Dense: No such file or directory` on pip install
+
 ### Version 2.2.4:
 
 * Fix #XX: Auto-generate config.h in setup.py so pip install from sdist works
