doesn't work on geoip2.database.Reader for generated mmdb

[complib2891]

i'm using python to read mmdb

geoip2.database.Reader is used to read mmdb like geolite2's versions
however the mmdb generated using mmdbmeld only works on maxminddb module instead of geoip2 module.

when using maxmiddb module, the output is quite limited, anyone knows how to make it works on geoip2 module?
