signature: Use a layered approach for signature verification.
Signature calculation has now moved out from being a package to top-level as a layered mechanism. In case of payload calculation with body, go-routines are initiated to simultaneously write and calculate shasum. Errors are sent over the writer so that the lower layer removes the temporary files properly.
