Adds the signer role with the given order to the list of signers for this
request. NOTE: The order refers to the 1-base index, not 0-base. This is
to reflect the indexing used by the HelloSign API. This means that adding
an item at order 1 will place it in the 0th index of the list (it will be
the first item).

@param role String
@param order int
@throws HelloSignException thrown if there is a problem adding the signer
role.
