[#26] object: Remake ExtendedHeader to field set
In previous version of the format ExtendedHeader consisted of one field Value, defined by oneof mechanism. Such a definition format give complete freedom when composing an object header, however, it did not allow strictly structuring the header format at the level of type syntax. Since the object has a well-defined structure in the system, this commit replaces the definition through oneof with a set of fields. As a consequence, storing a set of extended headers of the new type in the general header became redundant, so the repeated keyword was removed. Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
