oom problem when convert mmdb to json

[Paper-Dragon]

This command uses up all my memory, is it possible to optimize it while converting every ip?

memory: 32G
command:

mmdbinspect -db GeoLite2-City.mmdb  0.0.0.0/0 >> GeoLite2-City.json

I believe the current implementation reads all of the data into memory before encoding it to JSON. I do agree that it would be better to stream the records to stdout as we read them. This is a bit harder to do with the Go JSON library as it doesn't have streaming functionality built in, but it does seem doable.
