🚧 Upload zip extract import

[ildyria]

Add support of upload of single zip files.

⚠️ this is quite experimental, I tested locally that it works, however there are some caveats to know about.

1. The uploaded zip file will stay on your server unless it is properly extracted without faults (after which it is removed).
2. Similarly the extracted files from the zip will stay on your server unless they are properly imported without fault.
3. On import success, you will see in /path-to-lychee/storage/extract-jobs an empty folder prefixed with YmD so you know when it was created, making easier to clean up later.
4. ONLY THE FIRST LEVEL OF THE ZIP IS IMPORTED. See explanation below.

In other words, if you have

Something_Stupid.zip
├── img1.jpg
├── img2.jpg
├── img3.jpg
└── SubFolder
    ├── img4.jpg
    ├── img5.jpg
    └── img6.jpg

Only img1.jpg, img2.jpg and img3.jpg will be imported in Something Stupid album (note that _ is automatically replaced by space) and deleted from /path-to-lychee/storage/extract-jobs/yyyymmddSomething_Stupid.
The folder SubFolder will still be in /path-to-lychee/storage/extract-jobs/yyyymmddSomething_Stupid/SubFolder
