This is also the default compile setting on the master branch.
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_utilities/bootstrap_file.h` according to the comments.
The exporter will use the LMDB database as its source.
If you are still using an old style in-memory database (blockchain.bin), you will
have to either resync from scratch, or use an older version of the tools to export
it and import it.
