Import of third-party exports? #868
Description
It seems pretty easy to develop a framework to import third-party exports such as Google Takeouts, Apple Data & Privacy exports, etc. Just parse the takeout which by itself is low effort, then import them into their appropriate nextcloud app, like Google Chat -> NextCloud Talk, Google Keep -> NextCloud Notes, etc, although it does feel a bit out of scope and possibly high effort (although little effort and maintenance compared to direct API downloads and parsing), but it seems like something lots of people would do after "moving" to nextcloud.
