Make `ObjectReader` / `ObjectRangeReader` to track number of bytes read
and return:
* `io.ErrUnexpectedEOF` if the stream finished by the server before
the last byte of the payload was read.
* an error if more object payload size bytes was read.

PutContainer method takes `container.Container` structure
as an argument. This structure already contains session
token field, so there is no need in `prmSession` because it
duplicates session token definition.

This is done to prevent import cycles when `object` package needs any other
that requires `object.ID` or `object.Address`.

Define `WrongMagicNumber` type for which encapsulates the work with
incorrect network magic. Provide method to read/write the correct magic
(which is a status detail in NeoFS API V2 protocol).

Define `XPrm` type for each `X` client operation which structures
parameters. Export setters of each parameterized value. Emphasize that
some parameters are required. Make the client panic when the parameters
are incorrectly set. Get rid of vadiadic call options and `CallOption`
type. Improve documentation of client behavior.

In the latest NeoFS protocol update, each request is provided with a
network magic number. We have to provide the ability to set it on
the client.
Add `WithNetworkMagic` option constructor which accepts magic number.
Write the number to meta header of the all requests.

This option make client parse all NeoFS error statuses and return them as
errors from method calls (not as part of result structure). This is done
for applications that want to handle errors as it is customary in golang.
Default behaviour (construction client without new option) has not been
changed.

Make all `Client` methods to return structured values and error. Parse v2
status messages in all RPC and provide status getter from all result
structures. Returns status failures as status result instead of error.
Interface changes:
* all methods return `<method>Res` structure;
* rename some methods to be more clear;
* unify TZ and SHA256 objecy payload hashing in single method.
Behavior changes:
* client doesn't verify object header structure received via Object.Head.
If the caller was tied to verification, now it must do it explicitly.

Define base `Status` interface. Provide the functionality to distinguish
success and failure returns. Provide functionality to transport statuses
over NeoFS API V2 protocol. Support success `OK` and failure `INTERNAL`
returns.
