breaks if you use this with bitcore-lib-cash

[brad1121]

If you use this with bitcore-lib-cash you will get issues when trying to sign.

In particular

 throw new errors.InvalidArgument(argumentName, message, docsPath);
      ^
Invalid Argument: First argument should be an instance of PrivateKey

This is because bitcore-message requires bitcore-lib not bitcore-lib-cash as a dependency. Thus they reference a different instance of PrivateKey

Simple fix is to change the bitcore-lib dependency to bitcore-lib-cash to proceed.

Just a pain if you run npm update/install, you will have to change this back each time.
