[Feature] Expose additional EXIF fields for searching

The feature

Hi everyone and thank you very much for this awesome piece of free software!

Say I am using a photo management app such as DigiKam to recognize faces or pick tags and write the corresponding EXIF data (Subject, Region Name, Tags List, Keywords etc.) to my photos before sending them off to Immich. Wouldn't it be nice if Immich could search through these EXIF fields in addition to the ones already supported, such as the camera/lens model?

This would mean I could use Immich to find persons effortlessly—or photos matching any other tag, really—without having to rely on server-side implementations of facial/object recognition. Yes, this presupposes a well-organized photo library; but I know there are quite a few people besides me who does this, and given a feature such as Gallery Watcher, I think this would be a no-brainer.

I'm not familiar with TypeScript/Dart, nor do I have much time to spare at the moment, otherwise I'd love to have a crack at this. As far as I can tell, though, this should not be too difficult to implement. What do you all think?

Hello, are these properties preset, meaning the key are uniform or is it customized by the user in DigiKam?

[cycneuramus]

They are supposed to be uniform as far as I know; DigiKam was just an example here. As an aside, this feature (looking up photos by these kinds of EXIF tags) is present in PiGallery2, also written in TS. This seems to be a relevant part of the source code as far as extracting the metadata goes.
