Feature request: Support IPinfo database

[abdullahdevrel]

I work for IPinfo and we also provide our databases in MMDB format. I believe that our data can support the project.

I would like to request to add support for IPinfo's IP to Country database to the project. The database has the following features:

• It includes country and ASN information in the same database.
• It is updated daily, with zero compromise to accuracy. There is no range clustering, and the database provides full accuracy.
• The data granularity reaches individual IP level.
• The database comes in MMDB database format.
• It is licensed under CC-BY-SA 4.0, permitting commercial usage.
• Available file formats include: CSV, MMDB, JSON
• The data is tabular and unnested, making it very easy to use. The dataset includes both IPv4 and IPv6 in a single file.

Documentation: https://ipinfo.io/developers/ip-to-country-asn-database

Samples are available here: https://github.com/ipinfo/sample-database/tree/main/IP%20to%20Country%20ASN

The database can be downloaded simply by accessing the storage URI with an access token.

curl -L https://ipinfo.io/data/free/country_asn.mmdb?token=<YOUR_TOKEN> -o country_asn.mmdb

Let me know what you think. Thanks!
