2.5.6

New:
- Demo `demos/faceid` that utilizes multiple algorithms to validate input before triggering face recognition
- Type definitions rollup for `Human` and `TFJS`
- Optional module `liveness`  
  checks if input appears to be a real-world live image or a recording  
  best used together with module `antispoofing` that checks if input appears to have a realistic face
- Face masking option in `face.config.detector.mask`  
  result is shading of face image outside of face area which is useful for increased sensitivity of other modules that rely on detected face as input 
- Face crop option in `face.config.detector.cropFactor`
  result is user-definable fine-tuning for other modules that rely on detected face as input
