[FEATURE] location lookup without android.location.Geocoder

[Sjors]

On my Pixel 7 with GrapheneOS, the app is unable to look up my own location even though I gave it location permission. I just get a spinner.

I'm also not seeing the location for posts that has a g tag.

Looking at the source code, it seems you're using android.location.Geocoder to convert GPS coordinates (obtained from either the geohash or the device GPS) to a human readable name.

Unfortunately that doesn't work in GrapheneOS: GrapheneOS/os-issue-tracker#2302 (comment)

I remember that this feature used to work a year or so ago. I was able to post pictures with a geohash and find others. E.g. this post: https://njump.me/nevent1qvzqqqqqqypzpp59a0hkv5ecm45nrckvmu7pnk0sukssvly33u3wwzquy4v037hcqyg8wumn8ghj7mn0wd68ytnddakj7qgwwaehxw309ahx7uewd3hkctcqypwy03qsvapsyrp5gczglz0sxx4uss77knmkfaxgpn4wdxkj59euy9lj05d

I think I used Amethyst for that post, but I'm not 100% sure. However the use of Geocoder has been in place since 1098c31.

One very simple improvement could be to just show the raw geohash on existing posts, so at searching for other pictures in the same area will work.
