Downloaded CSV data missing, suggestion

[sry9681]

When looking at an address transaction history and the CSV download button is pushed, the resulting data has null values that can be quite important in terms of taxes, specifically the balance at the time of transaction. It may also be beneficial to include the price of Tezos at the time of that transaction along with separating out the 'amount' column into 'total_amount' and 'amount' such that 'total_amount' is the total balance of the account after that transaction and 'amount' is the change of total balance either sent or received during the transaction.
