fix: Write in place with exiftool

[m0lentum]

Fixes #623

This fixes issues with the way renamed files are detected from inode numbers, which would become desynced whenever exiftool was used. Any files that had their metadata edited would not be correctly detected as moved, and the web clipper would occasionally overwrite existing database entries, mistaking them for moved files.

Note: using inode numbers for detecting renames is still a potential source of errors because any external tool that overwrites files in this way will also similarly desync the database. This just fixes Allusion desyncing the database with its own operations.
