added new flag -literalMethods

[DefinitlyEvil]

Now users' are able to choose which obfuscators to use, by default all obfuscators are enabled.

  -literalMethods value
        Methods to use for literals. (simple, swap, split, shuffle, seed)

This is not something we want to add.

To add some context - more flags means the software is harder to use, test, and maintain. If any of the literal obfuscators are not fit for purpose, they should either be improved or removed entirely.

cool, gotcha!
