By default, the exporter will use the original in-memory database (blockchain.bin) as its source.
This default is to make migrating to an LMDB database easy, without having to recompile anything.
To change the source, adjust `SOURCE_DB` in `src/blockchain_converter/blockchain_export.h` according to the comments.
