Prefer snake-shift instead of a row-by-row shift

Per the assignment's instructions, the `Shift n` operation should treat
the *entire keyboard* like a cycle and shift that. I was erroneously
treating *each row* like a cycle and shifting those one-by-one.

This change fixes that. In addition, it also:
- Updates README.md with expected inputs and outputs
- Updates test suite
- Adds `split` dependency to {default,shell}.nix

 Looks like at least one of the characters in your input passage doesn't fit on our QWERTY keyboard:
 [1][2][3][4][5][6][7][8][9][0]
 [Q][W][E][R][T][Y][U][I][O][P]
