Bundle creation is tricky (didn't have time to correct it :().
You should create it with a dummy hash/uuid (Default::default()) and then call hash_slow().

this 10 should be a constant.
Maybe also some function like batch_number_from_u64() to isolate the % 10?

0,1,and 2 could be constants also documenting the format
eg:
/// col 1 contains bla bla
const COL_RAW_RLP_RX = 1
Is col 0 an arbitrary number? Is this some block number?
