Subject: [PATCH] Update Ciphers.mjs

Added a method called getMultiTapMap() which takes the arguments of toggle{int} and space_delim {string}.
This function creates a dictionary for the Multi Tap Cipher Encoding Scheme.
If the toggle is 1, it returns the dictionary directly.
else it reverses the dictionary and returns it, enabling it to be used in the decode operation.
