Allow Subprocess() with macro hash

[apotonick]

It would be great to be able to chugg an options hash (e.g. from a macro) into Subprocess().

options = {task: ..., ....}
step Subprocess(**options)

Ok, I found some places where I do

Railway.Subprocess(nested_deserializer).merge( ..)

Cool, I'll check this out!

My current hack:

def self.___Subprocess(options)
        if options.is_a?(Hash)
          Railway.Subprocess(options[:task]).merge(options)
        else
          Railway.Subprocess(options)
        end
      end
