Return `error` from all `ReadFromV2` methods in order to support
backward compatibility if message will be extended with some formatted
field.

There is a need to verify session data signatures calculated using
private session key. `Container` token encapsulates public session key,
so we need to provide method for signature check.

`Container` and `Object` types are transmitted in single `session.Token`
message. They differ only by session context.
Share common parts of the message in `commonData` struct. Embed struct
into `Container` and `Object`. Make `ReadFromV2` methods to check
protocol compliance. Make `Unmarshal`/`UmarshalJSON` to check field
format in case of presence only.

Merge `address` package into `oid` one. Bring `session.Object`
implementation into conformity with the NeoFS API protocol.

There is a need to duplicate session token owner, e.g. in container
created within the session. For such cases we need to have the ability
to receive session issuer.
Add `Container.Issuer` method. Transform `IssuedBy` to helper function.
