Tap images to expand them

[buresdv]

Introduction

As it is now, there is no way to tap on a picture and have it enter full screen.

Requirements

Add the possibility to tap on a picture to make it fullscreen. It should behave like in Photos, where tapping a picture expands it and then you can move it around and flick it away.

Should look like this: https://streamable.com/8xz0hv. Lemmy doesn't support albums, so there's no need to support more than one picture in a post.

What I Need

Rework the relevant files containing image views ( Post Item ) to support this feature. Also implement #61 to comply with Apple's guidelines around NSFW material.
