Update the access control example crypto library

assemblyscript/crypto.ts is now way more readable, faster (fixed-size arrays cannot really be fixed-size in AS, and classes can be more efficient) and smaller. Signatures and EC arithmetic are now done on the Ristretto group for yet another slight speedup.

 This code is used both by the JavaScript client code and by the AssemblyScript running on Terrarium. It implements the following cryptographic primitives in AssemblyScript:
 
-- The EdDSA signature scheme
+- Schnorr signatures (Ed25519 and over the Ristretto group)
+- Finite field arithmetic on integers and Curve25519 points
 - The HMAC-SHA-512 keyed MAC.
 
 Functions exported by this module can be called by the main server code using their native interface, since both are written in the same language.
