Add support for KeeLink - send passwords to devices without KeePass through QR code

[Dom324]

Problem
Sometimes one needs to login somewhere on an external device - e.g. a friends computer, meeting room at work... These devices usually do not have (any) KeePass installed (and furthermore storing the database on such device would be a security risk), which makes logging in difficult. Usual solutions include writing the password manually, or having an USB stick with a portable KeePass installation together with the database.

Describe the solution you'd like
KeePass2Android has a plugin called KeeLink , which enables user to share a password by scanning a QR code on this website https://keelink.fly.dev/ . The password is then sent encrypted to the said website and copied into users clipboard on the target device.

I could not find source code for the KP2A plugin, but the KeeLink repository has all the source code for the KeeLink server (supports self hosting), this should make it possible (and maybe not that difficult?) for KeePassDX to integrate with KeeLink.

Describe alternatives you've considered
Another plugin for KP2A exists https://www.inputstick.com/ , which solves the same problem, although with a hardware solution.
