Original mdbx txn_id might have gaps due to chain reorgs. When moving the data to snapshots we remove potential gaps in BlockBodyForStorage txn_id. This makes snapshot files identical across nodes because different nodes might encounter different chain reorgs. Note: the sequential numbering is called "TxNum" in erigon.
