Added `RandomAdversary` and the necessary auxiliary functions.
...
Random adversaries are created for `broadcast` and `honey_badger`. Random value generation was added for all type-dependencies of these algorithms, causing the `Rand` trait to be implement for a large portion of the codebase.
Additionally, `MessageWithSender` turned into an actual struct, making it much easier to handle. Tuple-like construction is still available through `MessageWithSender::new()`.

Add coin docs, change parity computation.
...
This makes the signature parity computation take into account all bits,
not just the last one of each byte.

Make SyncKeyGen NodeUid-aware.
...
This allows the caller to address nodes by ID instead of by index.
Also contains a few other minor changes that will be needed for
`DynamicHoneyBadger`.

Implement SyncKeyGen.
...
This is a _synchronous_ key generation algorithm. We will use it in
`DynamicHoneyBadger`, on top of `HoneyBadger` to satisfy the synchrony
requirements.
It can also be used independently e.g. on top of a blockchain.

Improve Hash impl for Ciphertext.
...
This formulation makes it harder to forget updating the `Hash`
implementation if the `Ciphertext` type changes.

Implement Hash for "public" cryptographic types.
...
This adds a `Hash` implementation for public keys, commitments,
ciphertexts and signatures — types that might make sense to be included
in special transactions. The `DynamicHoneyBadger` implementation will
require some of them.

Support serde by default.
...
This removes the `serialization-serde` feature, since serde is already
used internally and therefore a dependency anyway.
