trau-decode: refactor trau-hr-dump The desire is to create a companion program that will read hex lines representing TRAU-8k frames and then decode those frames in exactly the same way how we currently decode frames read from binary capture files. Hence the decoder portion of trau-hr-dump needs to be factored out.
