Prints out the `listincome` events as a CSV formatted file
Current csv_format options:
- koinly
- cointracker
- harmony (https://github.com/harmony-csv/harmony)
- quickbooks*
*Quickbooks expects values in 'USD', whereas we print values out
in <currency> (will be noted in the Description field). This won't work
how you'd expect -> you might need to do some conversion etc before
uploading it.
All amounts emitted as 'btc' w/ *11* decimals.
