Auto Load Facesets on LAUNCHING + XSeg Converter (built in)

[AlonDan]

1. 💡 Auto Load Facesets:

When launching Roop Unleashed,
It will be very useful if on SETTINGS there will be an option to SELECT a directory which will AUTO-LOAD the .fsz we created..

For example, I've created a directory called: "Facesets" and I place all the .fsz
Then I select ALL of them and Drag & Drop to Roop Unleashed.

Auto load will be a nice addition.

2. 💡 Xseg Converter built-in:

Another suggestion which will be VERY USEFUL is to add a dedicated TAB for
Converting XSeg to ONNX file with ease via the UI.

It will be also great if we'll be able to MANAGE manage multiple XSeg, and allow to select which one to use on the "Face Swap" main tab.

Since it's VERY SIMPLE to train XSeg also not need a high performance PC, it will be nice to make high quality XSeg masks and share with the Roop Unleashed community.

In time it will be nice if the best XSeg will just arrive with the latest version of Roop Unleashed, but also create and manage our own will be very useful 👍
