[Experimental] split stream header into 3 separate headers

[DavidBadura]

For the experimental stream store, only the stream name is required.

The requirement that 4 values ​​must be present, like the AggregateHeader has, dont exists in StreamHeader.
That's why I have now split this header into 3 headers, so we don't have to deal with nullable values.

• StreamNameHeader
• PlayheadHeader
• RecordedOnHeader
