iOS save images/files to files (and other system hooks; Apollo parity)

**Is your feature request related to a problem? Please describe.**
In Apollo for iOS, we could save images and other files directly (via context menu) into other apps (specifically Files for iOS) without first having to save into Photos.

**Describe the solution you'd like**
After long pressing on a photo or file, I would like to be able to save images/files into other system supported apps, namely Files for iOS, without first having to save it to Photos, and then moving it to Files.

**Describe alternatives you've considered**
Only current option is to save to Photos, then go into Photos and save where I really want the images/files. Very circuitous.
