Rail fence cipher new impl

[Chandrahas77]

What would you like to share?

Wan't to add implementation of rail fence cipher which is a classical type of transposition cipher.

Extra issue details

In the rail fence cipher, the plaintext is written downwards diagonally on successive "rails" of an imaginary fence, then moving up when the bottom rail is reached, down again when the top rail is reached, and so on until the whole plaintext is written out. The ciphertext is then read off in rows.

Additional information

Have implemented the above code with clean code and added tests to it. So if you approve this issue please provide me with the write access such that I can push code to feature branch and raise a pull request.
