Import from Google Analytics

[alexanderadam]

It seems that it's possible to export historical GA data.
This would make it easier for GA users to migrate to kindmetrics.

There're also a few tools and libraries available to export data.

Also two RubyGems but they're pretty old, so I guess they could be outdated.

See also how Matomo is doing this.

The best way would probably be also to integrate it in the settings or an onboarding process later on (i.e. Are you migrating from Google Analytics? Then get a token like described here and enter it here).
