Be able to import usage data from csv or json

[RiZKiT]

I like(d) the possibility to import usage data from google analytics. Sadly this feature will be no longer available for us, because we switch to a different tracking technology.

It would be nice to also support some generic data format like csv or json, which could be used to import usage data. Surprisingly I could not find any mentions in the repo or issue tracker about that.

Because Simple Analytics uses json, would be something like this (by just including browser_names array only) be enough? https://simpleanalytics.com/simpleanalytics.com.json?version=5&fields=browser_names

Update: Seems not, there has to be an agents field in the json. So the question which kind of format is needed is still open or the option for a generic csv/json format, independent from simple analytics.
