LiveDB Export Iterates accounts twice

[kjezek]

At the moment, when exporting liveDB, accounts are iterated twice. First time, they are iterated to find referenced codes, second time, they are iterated to do actual export them.

This is time consuming.

It should be possible to find referenced codes as part of exporting accounts. The only obstacle is, that codes are written in the file before MPT payload.

It would need either prepend the codes before the export, or check if the codes can be stored after the MPT payload.
