[#26] object: Replace Transform header with Split

Browse source 
This commit replaces Transform message with SplitHeader in oneof definition
of Value field of Header message. The latter, unlike the first, carries
complete information about the generation of the object by splitting the
payload. As a result, the message is deleted as no longer used.
