[Feature suggestion]Support for reading Wifi credentials

[martonmiklos]

It would be great if the CodeReader could read Wifi credential QR codes, and would offer the connection to those access points (or offer storing the credentials if the access point is not visible).

I have not managed to find the standard for the format it yet, this is the closest info what I could find:
https://github.com/zxing/zxing/wiki/Barcode-Contents#wi-fi-network-config-android-ios-11

This site claims to be using this format and it is said to be supported by the Android and iOS implementations.

Although I do not know if it is possible to add Wifi access point information to Sailfish OS through API. Any information on this topic is welcome.
