There was no ability to read qr codes contained in image files. This could lead to confusion in some contexts, as `on_file_input()` of ScanQRTextEdit will read the whole content of the file (instead of looking for qr codes). The revealer plugin for example generates png files containing qr codes and uses the `ScanQRTextEdit` to get user input, for the user it would seem logical to click on 'Read from file' to load the generated file, however this will result in the wrong data being loaded. Having the option to explicitly load a QR from file makes this clear. Also it seems useful, especially considering reading QR from screenshots doesn't work on wayland.
