Description

Summary

Add the ability to specify different alphabets for use with the Affine and Atbash cipher operations.

Possible solutions

The editableOption argument type could be useful. See 'To Base64' for an example of how this works. You could specify a few default alphabets (Latin, Hebrew etc.) whilst still allowing users to enter a custom alphabet of their choosing.

Research direction
Examine the current implementation of Atbash and Affine ciphers in the CyberChef codebase, likely within src/core/operations. Study the 'To Base64' operation to understand how 'editableOption' is used for custom alphabets. Implement similar functionality for the two ciphers, providing default alphabets and allowing user input. Refer to the linked example for guidance.
