Feature request: Filter reports/apps by permissions

[kytta]

It would be of great help, if there was a possibility to filter the reports based on the permissions the app requires. My use case, for example, would be to only inspect those apps that require microphone access. It'd also be great if it would be exposed as an API endpoint, something along the lines of /api/reports/?has_permission=android.permission.RECORD_AUDIO.

This was first addressed in #2 and later in #383, but hasn't been implemented yet.
