It is never sent on its own, so it doesn't need to be a `Message`.
* Static constructor `read(protocolVariant)` replaces the native constructor that deserialized
from a payload.
* `write()` helper replaces `bitcoinSerializeToStream()`.
* `serialize()` and `getMessageSize()` helpers replace `bitcoinSerialize()`.

Includes a test.
Rather, use `InetSocketAddress` and `Services`.
This makes `time` in `PeerAddress` a required field. It also drops
support for TORv2 addresses in `VersionMessage` (if that was ever
a thing).
* Rename `getBitcoinProtocolVersion()` to `intValue()`
* Deprecate `NetworkParameters.getProtocolVersionNum()`. This eliminates
what seems to be an unnecessary level of indirection.
* Add tests.
This will also help eliminate a dependency on `NetworkParameters` in some places.

* A static constructur `read()` replaces the native constructor that deserialized

* A `write()` helper replaces `bitcoinSerializeToStream()`.
* A `serialize()` helper replaces `bitcoinSerialize()`.
This comes with tests.
* A static constructur `read()` deserializes from a payload.
* A `write()` helper replaces `bitcoinSerializeToStream()`.
* A `serialize()` helper gets the serialized bytes.
This comes with a test.
