v2ray geoip data has problemic license

[linsui@inbox.lv]

Hi,

V2Fly project provides a geoip data file in 
https://github.com/v2fly/geoip. The license is declared as CC-BY-SA-4.0 
but it uses the data from GeoLite2, which is licensed under an EULA 
https://www.maxmind.com/en/geolite2/eula. The EULA looks like not a 
free license.

Debian packages the data file in the v2ray package. And Debian marks 
the data as MIT which is also wrong. Could you please check the license?

Thanks!

Yours,
Linsui
