Expand description

Derive a super segment for a block with a specified parent block number.

For block n shard segment roots of confirmed blocks n - block_confirmation_depth - shard_confirmation_depth ..= n - block_confirmation_depth are read (see ConsensusConstants::block_confirmation_depth and ConsensusConstants::shard_confirmation_depth).
