Credential error with geoip2 v2.9.0

[mathieuimbert]

In the newest geoip2 version v2.9.0, they now use "account" instead of "user".

It means that the client factory should include both userId and accountId in order to support 2.9.0 and the previous versions.

I am not sure if this repository is still maintained, I'll be happy to create a PR is someone can take a look.

@mathieuimbert thank you for pointing, I'll take a look soon.
