#180 Remove duplication of workflow inputs and outputs #minor Pull request opened by sonjaer TL;DR Currently, users need to define outputs and inputs twice through SdkWorkflow<InputT, OutputT> and in builder.inputOf() and builder.output() which forces users to specify duplicate information which is error prone. This PR removes the ability to specify inputs/outputs through the builder.
