Support license checking and in-app purchases without the Google Play Store

Is your feature request related to a problem? Please describe.
In order to get license checking and in-app purchases to work you need the Google Play Store app. It would be good if microG didn't depend on the Google Play Store app.

microG already support license verification but you must update both microG Services and microG Companion and enable the corresponding options in microG settings.
It may not work with all apps but it already work in many cases.

But doesn't that need Google Play Store to be installed?

No, microG Companion (new name of FakeStore) is the replacement of Google Play Store.
It doesn't allow to download apps but it support some things like license verification (it weren't supported at the start but now it is).

Note: It must be enabled in microG settings otherwise it doesn't work.

Noteworthy, it doesn't work with the in-app purchase ordered not in the current device.
