Label the hinged tetrominoes
- Label the hinged tetrominoes - [FINALIZED]
- Given a hinged tetromino, give it a unique, consistent label.
- ## Tetrominoes
- A ***[tetromino]*** is a connected subset of the square tiling, composed of 4 squares, where connection can only be **edge connection**.
- Here are the 5 tetrominoes:

- ## Hinged tetrominoes
- A ***[hinged tetromino]*** is a connected subset of the square tiling, composed of 4 squares, where connection can be **edge connection** or **corner connection**.
- Here are the 22 hinged tetrominoes:

- ## Input
- - A 4 by 4 grid containing a hinged tetromino.
- - You may take input in any convenient format that does not include full or partial precalculation.
- - For example, this could be a string or sequence of strings, a 1 or 2 dimensional list/array/vector, a sequence of coordinates, or a 16 bit variable where each 1 bit represents part of the hinged tetromino and each 0 bit represents part of the background. A variable with more than 16 bits where only 16 of the bits are used would also be acceptable.
- ## Output
- - A label for the hinged tetromino.
- - The label for each hinged tetromino can be anything you choose, including nothing (no output).
- - Each label must be unique (it must not be the label for any other hinged tetromino).
- - Each label must be consistent (a given hinged tetromino must always result in the same label, regardless of rotation, reflection, or translation).
- ## Scoring
- This is a [code golf challenge]. Your score is the number of bytes in your code.
