Fix CallWithoutOpaque function clause error on OTP-28

Fixes #561 by adding support for the new 5-argument format used by
OTP-28 while maintaining backward compatibility with the legacy
4-argument format.

The OTP-28 format passes additional type information as a 5th argument
which we ignore for formatting purposes, using the same expected_triples
data structure as before.
