Submission: immich plugin

[Gilles Caulier]

Hi Christian,

There is no problem to compile this code under Linux (here arm64):

A first look to the GUI revelate some improvements to do :

- the layout is broken on the top/left.
- I don't understand the interface, how to start, and how to do it. A
better mapping of the widget can help the users to quickly drive the tool.
- The thumbnails : you don't use the cache mechanism from digiKam. Looks
like HEIF is not rendered, where digiKam supports it very well.
- No action button, Hel, close, upload, etc, typically on the bottom of the
dialog.

I look quickly at the code improvements that can be done a lot, as private
classes C++ objects can be hidden. There is a cpp file more than 100Kb. The
cpp must be separated by feature to help in the code maintenance. Look how
i do with the 3rd party Gmicqt plugin that i wrap in this repository:

https://github.com/cgilles/digikam-gmic-qt/tree/master/src/bqm

It's usual to limit the cpp file size to 10-20 Kb when it's possible. .h
cannot be cut in small parts.

I recommend also to pass the open source static analyzers, as cppcheck or
clazy. Look at the scripts here :

My best regards

>> - Export of the digiKam selection to the Immich library or album.
>> - Metadata round-tripping through XMP sidecars (tags, rating, caption,
>> GPS), which one mechanism both applications read and write. Metadata
>> edited on either side is synced onto the existing Immich asset rather

>> - Edited files are recognized as new versions of photos already in
>> Immich (by name, capture time, dimensions and a pixel comparison) and

>> it has unit tests for its pure logic plus contract tests against a stub
>> server.

>> I use it against my own server, and I am prepared to help maintain it,
