Refactor bytestream configuration for component accumulator
This pull request started from the quest to add a CI test for ByteStreamMetadata reading and writing. The configuration module to read from and write to bytestream was functional but could use improvement. Since my investigation has taken me to find out whether something is missing in the Read configuration of bytestream it seemed like a good plan to spruce up the configuration before doing any more work on it.
