Bogdan-Ștefan Neacşu c9dce0c1da Feature/consumable bandwidth (#766)
* Set actual value for bandwidth

Also put it as a public attribute, such that it can be actively used
by the credential consumer

* Switch from sending Attribute structs to sending the actual attribute bytes over the wire

* Add atomic bandwidth value to gateway

* Consume bandwidth based on the mix packet size

* Use Bandwidth struct for specific functionality

* Move bandwidth code outside the dependency path of wasm client

* Use u64 instead of AtomicU64, as the handling is not parallel

* Update Cargo.lock after rebase

* Replace String error with HandshakeError

* Add CoconutInterfaceError to coconut-interface

* Format the new error in tauri client

* Remove  from default, as wasm client doesn't build

* Put public key as init argument...

... for the public attributes of the credential

* Use the hash_to_scalar function to make public key into attribute

Use the function from cli-demo-rs from https://github.com/nymtech/coconut
to make the identity public key into a public attribute.

* Replace vector with array for InitMessage

As we know beforehand the size of the keys, we can use fixed size array
instead of vectors. This eliminates the need for a prefixed length in
the serialized form of the InitMessage structure and enables a easy
deserialization of the remote identity before the actual bincode
deserialization that we do in the handshake process.

Before this, the `extract_remote_identity_from_register_init` function
attempted to deserialize into a public key the length-prefixed public key
received from the client, thus failing sporadically with a `Cannot decompress
Edwards point` error.

* Pass public and private attributes to state `init` instead of PublicKey

* Make tauri call with dummy attributes

* Make clients call with their keypairs

* Revert "Make clients call with their keypairs"

This reverts commit b348f47f7a.

* Put dummy, bandwidth private attribute
