62b61107e0 ENHANCED: Suspend propagation during filtering in scalar product constraints. 
This allows subsequently invoked constraints to take the entire
filtering results into account, instead of being invoked when the
obtained information is not yet entirely used.

It speeds up programs such as the one in:

47ec5eb6c6 ENHANCED: Use crrl for Ed25519 signing and signature verification. 
The main motivation for this change is the introduction of the newly
available predicate ed25519_seed_keypair/2, allowing to generate a key
pair from a given seed. In this way, a key pair can be dynamically
generated from (for example) a password, using crypto_password_hash/3
in combination with crypto_data_hkdf/4 to generate the seed. The
advantage of this method is that the private key need not be stored at
all anywhere.

It is not possible to add a corresponding feature to ring, since it is
closed as "not planned": https://github.com/briansmith/ring/issues/1003

I also used this opportunity to move more of the logic to Prolog. We
now have total control of the key pair representation, and I also
changed the representation to conform to the PKCS#8 v2 standard,
something that only later ring versions do, while still being
backwards compatible with tools that produce a wrong representation
including earlier ring versions.

Another great advantage we get from this change is that the Ed25519
predicates now also run on the 32-bit and WASM versions of Scryer.

8cb4dfef62 ADDED: term_si/1, true for terms 
One use case is to ensure that once/1 is safe to use:

    term_si(Goal),
    once(Goal)

In such cases, Goal is ground and can yield at most one solution,
therefore once/1 does not remove any solutions.
